This Culver's pork tenderloin sandwich recipe delivers the same tender, smoky magic you love from the restaurant—right in your kitchen. The secret lies in a herb-infused brine that keeps the pork impossibly juicy while developing that signature caramelized crust.
After years of perfecting pork at Atlanta's Smoky Pig, I've cracked the code for restaurant-quality results at home, including that crisp celery crown that makes it unforgettable.
The process starts with a simple brine of apple cider vinegar, brown sugar, and fresh herbs that tenderizes the meat from the inside out. You'll roast it to medium-rare (130°F internal temp) for maximum tenderness, then slice it against the grain for those melt-in-your-mouth strips.
The toasted brioche bun gets slathered with smoky herb gravy—a game-changer that ties everything together—and finished with crisp celery sticks that add crunch and freshness.
What you end up with is a sandwich that's restaurant-perfect: juicy, tender pork with crisp edges, a toasted bun that holds up to every bite, and that perfect balance of smoky gravy and fresh celery.
The gravy isn't just a topping—it's the star, infused with rosemary and thyme that complement the pork beautifully. This is the kind of sandwich that disappears faster than you can say "second helping."
Pair it with classic sides like crispy onion strings or a simple green salad to complete the meal. The beauty of this recipe is its flexibility—make it for a weeknight dinner or a weekend gathering, and it'll be the centerpiece of the table every time. Let's get cooking!
Ingredients for culver's pork tenderloin sandwich
These 14 ingredients bring Culver's signature pork tenderloin magic to your kitchen.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of fat |
| Apple Cider Vinegar 🍎 | ¼ cup | For the herb-infused brine |
| Light Brown Sugar 🍚 | ½ cup | Packed, for tenderizing |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Garlic Cloves 🧄 | 6 cloves | Minced, for brine and gravy |
| Salt 🧂 | 1 tbsp | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | 1 tsp | Freshly cracked |
| Brioche Buns 🍞 | 4 whole | Store-bought or homemade |
| Celery Stalks 🧅 | 2 whole | Thinly sliced, for crown |
| Unsalted Butter 🧈 | ½ cup | Cold, for basting |

The pork tenderloin is non-negotiable—center-cut with that fat trimmed off for perfect tenderness. Costco or Whole Foods have great pre-trimmed options, but if you're cutting it yourself, look for a uniform shape. Fresh herbs make all the difference here: grab rosemary and thyme from the grocery store's refrigerated section (they'll be more potent than dried). The apple cider vinegar should be raw, unfiltered—the kind you'd drink. If you can't find it, white vinegar works in a pinch, but the flavor won't be quite as complex. And for the garlic, peel it fresh—jarred minced garlic has a metallic aftertaste that ruins everything. Trust me on this.
No fresh rosemary? Dried works at half the amount, but it won't have that same piney aroma. Running low on celery? Green onions or shallots can add a similar freshness to the crown. The brioche buns? Store-bought is fine—just slice them open and toast them in the oven for 3-5 minutes before assembling. For the gravy, if you don't have chicken broth, vegetable broth plus a dash of soy sauce gets you close. And if you're feeling fancy, swap the olive oil for brown butter**—it adds a nutty depth that pairs perfectly with the pork. The key is keeping everything balanced: smoky, fresh, and crisp all at once.
This pork keeps beautifully—reheat slices in a skillet with a splash of broth for that same restaurant-quality moisture. The gravy reheats well too, but add a little extra broth if it thickens up. Store the assembled sandwiches (without the celery crown) for up to 2 days in the fridge, but honestly? They're better fresh. The celery crown loses its crispness after an hour, so add it just before serving. For a crowd, double the pork and gravy—just make sure you've got enough buns! I always keep a few extra on hand, because seconds happen fast with this one.

Step-by-step instructions for Culver's pork tenderloin sandwich
Transform simple ingredients into restaurant-quality pork with tender meat, rich gravy, and crisp celery crown.
Create the Herb-Infused Brine
In a bowl, whisk together the 0.25 cup apple cider vinegar, 0.5 cup light brown sugar, 0.25 cup chopped fresh rosemary, 0.25 cup chopped fresh thyme, 6 minced garlic cloves, 1 tablespoon salt, and 1 teaspoon cracked black peppercorns. This mixture creates a flavor-packed brine that tenderizes the pork while infusing it with aromatic herbs.
Place the 1.5 lb pork tenderloin in a resealable plastic bag and pour the brine over it, massaging the pork to ensure even coating. Seal the bag and refrigerate for at least 4 hours (overnight works best). The acidity from the vinegar breaks down muscle fibers, while the sugar and herbs create that signature Culver's flavor profile.
Roast the Pork to Perfect Tenderness
Preheat your oven to 425°F. Remove the pork from the fridge and let it sit at room temperature for 30 minutes while you prepare your roasting pan. Pat the pork dry with paper towels—this step is crucial for achieving that crisp exterior.
Place the pork on a rack in a roasting pan and roast for 25-30 minutes until the internal temperature reaches 145°F (use a meat thermometer). The pork should feel tender when pressed gently with tongs. Let it rest for 10 minutes before slicing—this resting period ensures juicy, evenly cooked meat that won't fall apart when you cut into it.
Prepare the Smoky Herb Gravy
While the pork rests, melt 0.5 cup cold unsalted butter in a skillet over medium heat. Add the sliced 2 whole celery stalks and cook for 3-4 minutes until softened. Stir in 2 tablespoons all-purpose flour and cook for 1 minute to remove the raw flour taste.
Slowly whisk in 0.5 cup chicken broth, scraping up any browned bits from the bottom of the pan. Bring to a simmer and cook for 5-7 minutes until the gravy thickens to a sauce-like consistency. The gravy should coat the back of a spoon smoothly—this is your signature Culver's smoky herb gravy that ties everything together.
Assemble with Crisp Celery Crown
Slice the rested pork into ¼-inch thick medallions. Toast the 4 whole brioche buns lightly in a dry skillet for 1-2 minutes per side until golden brown. Spread each bun with a generous spoonful of the smoky herb gravy.
Layer the pork medallions on the bottom half of each bun, then top with additional gravy. Place the top bun on each sandwich and press gently. For the celery crown, arrange the sliced celery in a circular pattern on top of each sandwich, pressing lightly to create a crisp, decorative crown. Serve immediately while the pork is still warm and the celery remains crisp.
Pro Tips For Making Culver'S Pork Tenderloin Sandwich
- Trim the Fat First: Pork tenderloin’s lean, but a thin layer of fat or silver skin can keep the seasoning from sticking. Use a sharp knife to slice off any visible fat or skin before you even think about the marinade—this isn’t the time to be gentle.
- Marinate Overnight (Yes, Really): I used to rush this, thinking 30 minutes would do. Wrong. The apple cider vinegar and rosemary need time to tenderize and infuse. Toss the pork in a ziplock with the marinade (vinegar, brown sugar, herbs) and let it sit in the fridge for at least 12 hours—I do 24 if I remember. The sugar will caramelize better, and the meat stays juicy.
- Don’t Overcrowd the Pan: Searing small batches is the thing that matters most here. If you dump all the pork in at once, it’ll steam instead of sear, and you’ll end up with sad, gray meat. Work in two batches max—crowding kills the crust you’re after.
- Use a Meat Thermometer: Pork tenderloin is small and cooks fast, but guessing leads to dryness. Pull it at 140°F—any higher, and it’ll jump to 145°F while resting. Let it sit 5 minutes under foil before slicing, or you’ll lose all that juicy goodness to the cutting board. (Yes, even if you’re impatient like me.)
Dietary considerations for this culver's pork tenderloin sandwich
Gluten-Free Adaptation
For a gluten-free version, replace the brioche buns with a gluten-free brioche blend from brands like King Arthur or Canyon Bakehouse. These blends mimic the texture of traditional brioche while keeping the sandwich cohesive.
I’ve tested both and recommend toasting them for 2-3 minutes per side in a dry skillet to achieve that same golden crust. The smoky herb gravy can stay as-is since it’s naturally gluten-free, but always check your chicken broth label for hidden gluten additives. 🥖
Dairy-Free Options
Skip the butter in the gravy and use olive oil or vegetable oil instead—just ½ cup total—to sauté the celery and flour. For richness, stir in 2 tablespoons dairy-free butter (like Miyoko’s) or a splash of unsweetened almond milk at the end.
The celery crown remains crisp and fresh, and the pork stays juicy without any dairy interference. Trust me, the flavor stays bold and satisfying. 🌿
Lower-Carb Adjustments
Swap the brioche buns for lettuce wraps or low-carb tortillas (like Mission Carb Balance) to cut carbs significantly. For extra crunch, add ¼ cup shredded cabbage between the pork and lettuce layers.
The smoky herb gravy can be thickened with xanthan gum (½ tsp) instead of flour, and you’ll still get that same rich, velvety texture. This version keeps the sandwich hearty while fitting into keto or low-carb diets. 🥬
Allergen-Friendly Tips
If nut allergies are a concern, avoid almond milk in the gravy and stick to coconut milk (just 1 tbsp) for creaminess. For soy-sensitive diets, ensure your chicken broth is soy-free—Pacific Foods makes excellent soy-free options.
Always double-check labels, especially for hidden soy in broths or gluten in seasonings. I keep a separate set of utensils and cutting boards for allergens to avoid cross-contamination. Safety first! 🛡️
Protein Swaps
For a chicken version, use a 1.5 lb boneless chicken breast and brined it the same way (just reduce the brine time to 2 hours). For beef lovers, swap in 1.5 lb sirloin—sear it first for 2 minutes per side before roasting to 145°F.
The herb gravy works beautifully with either, but adjust the roasting time: chicken cooks faster (about 20 minutes), while beef needs 30-35 minutes. The celery crown and gravy remain the same, keeping the sandwich’s signature texture. 🥩

Frequently asked questions
Why does the pork tenderloin need to rest before slicing?
Resting the pork for 10 minutes after roasting lets the juices redistribute throughout the meat. If you slice it too soon, all those delicious juices will run out, leaving you with dry, tough slices. This is especially important for pork tenderloin, which has less connective tissue than other cuts. The 145°F internal temp ensures safety while keeping it tender.
Can I make the herb gravy ahead of time?
Yes! The gravy actually tastes better the next day. Store it in an airtight container in the fridge for up to 3 days. When reheating, add a splash of chicken broth to thin it out if it thickens too much. Just stir over medium-low heat until warmed through—no need to cook it again. Perfect for meal prep!
What's the secret to crisp celery crowns that don't get soggy?
Slice the celery just before assembling the sandwiches and pat it completely dry with paper towels. Arrange the slices in a tight circle on top of the sandwich and press gently with a spatula. The key is serving immediately—if you make them ahead, the celery will lose its crispness within 15 minutes. For extra crunch, chill the assembled sandwiches for 10 minutes in the fridge before serving.
Is there a way to make this sandwich without a brioche bun?
For a lighter option, use toasted sourdough or hoagie rolls. If you want to keep it close to the original, try potato rolls (toasted) or even lettuce wraps for a low-carb version. Just make sure whatever you use can hold up to the juicy pork and gravy. The brioche's buttery texture is ideal, but these alternatives work beautifully too.
How do I fix pork that's too dry after cooking?
If your pork turns out dry, try this quick fix: Slice it thinly against the grain and quickly sear the slices in a hot skillet with 1 tablespoon butter and 1 tablespoon chicken broth for 1-2 minutes per side. The moisture from the pan will help revive the texture. For future attempts, use a meat thermometer and pull the pork at 145°F—don't overcook!
