Ingredients for pork tenderloin recipe crock pot cream of mushroom

Pantry staples plus two specialty touches—crispy celery crowns and slow-cooked pork. Simple enough for weeknights, fancy enough for guests.

Ingredient Amount Notes
Pork Tenderloin 🥩 1 ½ lb Center-cut for even cooking
Cream of Mushroom Soup 🍄 2 cups Condensed, not ready-to-serve
Garlic Cloves 🧄 4 cloves Minced for even distribution
Celery Stalks 🧅 4 whole For crowns, cut into 1-inch pieces
All-Purpose Flour 🌾 ½ cup For dredging celery crowns
Large Eggs 🥚 1 whole Beaten for egg wash
Vegetable Oil 🫒 ½ cup For frying celery crowns
Salt 🧂 1 tsp Kosher or sea salt
Black Pepper 🌶️ ½ tsp Freshly ground preferred
Dried Thyme 🌿 1 tsp Or 1 tbsp fresh thyme
Dried Parsley 🌿 1 tsp For garnish
Butter 🧈 2 tbsp For sauce richness
Heavy Cream 🥛 ¼ cup For velvety texture
Cornstarch 🌾 1 tbsp For thickening sauce

The pork tenderloin is the star here. Look for a center-cut piece—it's more tender and cooks evenly. Costco or Walmart usually have great prices on these, but any grocery store will do. If yours is uneven, trim it to about 1.5 pounds before cooking. The celery crowns? Fresh celery with tight stalks makes the best crispy topping—avoid those rubbery, stringy ones. I like to buy organic celery from Whole Foods when I can, but regular grocery store celery works fine too. Just make sure it's crisp and green, not yellowing at the base.

No cream of mushroom soup? Make your own quick version with mushrooms, chicken broth, and a splash of cream. Fresh thyme is ideal but dried works at one-third the amount. The heavy cream can be swapped for coconut milk if you're avoiding dairy, though the texture will be slightly different. For the celery crowns, panko breadcrumbs make a great alternative to flour—just skip the egg wash. If you're short on time, you can even bake the celery crowns at 400°F for 15 minutes instead of frying, though they won't be quite as crispy.

This sauce gets better as it sits, so make it a day ahead if you can. Store leftovers in the fridge for 3-4 days—the pork stays tender, and the sauce thickens up nicely. For freezing, portion the pork and sauce separately. The celery crowns? Best eaten fresh, but you can reheat them in the oven at 350°F for 5 minutes if needed. I always make extra because they disappear fast—great for snacking or adding to salads later in the week.

Step-by-step instructions for crock pot pork tenderloin with creamy mushroom sauce

This method delivers melt-in-your-mouth pork with a velvety sauce and crispy celery crowns.

1

👨‍🍳 Step 1: Prepare the Celery Crowns for Crunch

Cut the 4 whole celery stalks into 1-inch pieces, keeping the leafy tops attached (this is your crown). In a bowl, whisk together the 1 whole large egg, 1 tsp salt, and 0.5 tsp black pepper. Add the celery pieces and toss until evenly coated.

Transfer to another bowl and dredge in the 0.5 cup all-purpose flour, shaking off any excess. Heat 0.5 cup vegetable oil in a skillet over medium-high heat until shimmering. Fry the celery crowns in batches for 2-3 minutes until golden brown and crispy. Drain on paper towels and set aside—they'll add incredible texture to your dish.

2

🔥 Step 2: Season and Sear the Pork Tenderloin

Pat the 1.5 lb pork tenderloin dry with paper towels—this ensures a better sear. Season generously with 1 tsp salt, 0.5 tsp black pepper, 1 tsp dried thyme, and 1 tsp dried parsley. Heat 2 tbsp butter in a skillet over medium-high heat until foaming.

Sear the pork on all sides for 2-3 minutes per side until golden brown. You're not cooking it through—just creating that beautiful crust. Transfer the seared pork to your crock pot and add the 4 cloves minced garlic to the skillet. Cook for 30 seconds until fragrant, then scrape up all the browned bits from the bottom of the pan.

3

🥘 Step 3: Build the Creamy Mushroom Sauce

Pour the 2 cups cream of mushroom soup into the crock pot with the pork, along with the garlic and browned bits from the skillet. Stir gently to combine. Add the 0.25 cup heavy cream and 2 tbsp butter (if not already in the crock pot). The sauce should look rich and inviting.

In a small bowl, whisk together the 1 tbsp cornstarch with 2 tablespoons water to create a slurry. Stir this into the crock pot mixture. Cook on low heat for 4-5 hours (or high heat for 2-3 hours) until the pork reaches 145°F internal temperature and is fork-tender.

4

🍽️ Step 4: Finish and Serve with Crispy Toppings

Remove the pork from the crock pot and let it rest for 10 minutes on a cutting board. Slice into ½-inch thick medallions. Skim any excess fat from the sauce in the crock pot, then adjust seasoning if needed. The sauce should coat the back of a spoon and be velvety smooth.

Serve the pork medallions topped with the creamy mushroom sauce and the crispy celery crowns you prepared earlier. Garnish with additional dried parsley for color and freshness. The contrast of tender pork, rich sauce, and crunchy celery crowns makes this dish truly special.

Pro Tips For Making Pork Tenderloin Recipe Crock Pot Cream Of Mushroom

  • SEAR THE TENDERLOIN FIRST: I learned this the hard way—skipping the sear means your pork will turn out bland and pale. Pat the tenderloin dry, then hit it with a hot pan for 2-3 minutes per side until golden. The crock pot will handle the slow cook, but that crust locks in flavor.
  • USE FLOUR TO THICKEN MID-COOK: After the first hour, sprinkle 1-2 tablespoons of all-purpose flour over the soup mixture. Stir it in and let it cook another 30 minutes—this prevents a watery finish and gives the sauce body without clumping. (Yes, even if you’re impatient like me.)
  • CHOP CELERY SMALLER THAN YOU THINK: Big celery chunks turn to mush and make the dish look messy. Dice them into ¼-inch pieces—they’ll soften but stay recognizable, and the texture actually improves the soup’s mouthfeel. Trust me, your future self will notice.
  • SKIP THE GARLIC PEELING STEP: Peeling garlic cloves before mincing is overrated. Just smash each clove with the flat side of your knife, then chop through the skin—it’ll slide right off. Saves time, and you won’t end up with garlic bits hiding in your teeth. (We’ve all been there.)

Health benefits of this pork tenderloin recipe crock pot cream of mushroom

Lean Protein Power

Pork tenderloin is one of the leanest cuts of pork, packing 24 grams of protein per 3-ounce serving with just 150 calories. This makes it an excellent choice for anyone watching their calorie intake or building muscle.

Unlike fattier cuts, tenderloin absorbs flavors beautifully while staying tender and juicy—perfect for slow cooking. 💪

Mushroom Sauce Nutrients

The cream of mushroom sauce adds nutritional depth with vitamin D (from mushrooms) and B vitamins (from cream of mushroom soup). Mushrooms also contain selenium, an antioxidant that supports your immune system.

When you add the heavy cream, you get a dose of vitamin A and calcium, making this dish a surprisingly well-rounded meal.

Low-Fat, High-Flavor

This recipe keeps saturated fat minimal while delivering maximum flavor. The slow cooking process tenderizes the pork without needing extra oil or butter. The celery crowns add a crispy texture without adding significant calories, making this a satisfying yet lighter option compared to traditional fried pork dishes.

I love that it feels indulgent but still aligns with balanced eating.

Digestive Benefits

Celery is a natural diuretic and contains fiber that supports digestion. The celery crowns you fry up add a satisfying crunch while providing vitamin K and folate.

Plus, the slow-cooked pork is easier to digest than quickly seared cuts, making this dish gentle on your stomach while still being flavorful. It's one of those meals that feels good all around!

Meal Prep Friendly

This dish stores beautifully in the fridge for 3-4 days, making it perfect for meal prep. The protein stays tender, and the sauce thickens up nicely overnight. I often double the recipe because leftovers reheat wonderfully—just warm the sauce and pork together for 2-3 minutes on the stove.

The celery crowns can be made ahead and reheated in the oven if needed, so you're not stuck with soggy toppings.

Balanced Macros

Each serving delivers a balanced mix of protein, healthy fats (from the cream and butter), and complex carbs (from the celery and any side dishes). Pair it with roasted sweet potatoes or quinoa to round out your plate with fiber-rich carbs.

The umami from the mushroom sauce keeps things interesting without relying on heavy sauces or excessive salt. It's comfort food with a nutritional boost! ✨

Frequently asked questions

1

Can I use fresh mushrooms instead of cream of mushroom soup?

For a homemade version, sauté 8 oz sliced mushrooms with 2 cloves minced garlic in 1 tbsp butter until soft. Add 1 cup chicken broth and 2 tbsp heavy cream, then simmer until thickened. Use this mixture to replace the soup in the recipe—it'll give you a deeper mushroom flavor!

2

How do I know when the pork tenderloin is fully cooked?

Use a meat thermometer to check for 145°F internal temperature at the thickest part. The pork should pull apart easily with a fork and have no pink center. If you don't have a thermometer, cut into the thickest part—juices should run clear, not pink or red. Never guess with pork!

3

Can I make this recipe in an Instant Pot instead?

Yes! Sear the pork first, then add all ingredients except the celery crowns. Cook on high pressure for 20 minutes, then quick-release. Finish with the cornstarch slurry and let it thicken off-pressure. The celery crowns can be fried separately and added just before serving. The texture will be slightly different but still delicious!

4

What's the best way to reheat leftovers?

Place pork and sauce in a skillet over medium-low heat for 3-4 minutes, stirring occasionally. Avoid microwaving—it makes the pork rubbery. For the celery crowns, reheat in a 350°F oven for 5 minutes to restore crispiness. Store leftovers in an airtight container for up to 3 days.

5

Why did my pork turn out dry?

Overcooking is the most common cause. Pork tenderloin cooks quickly—remove it when it reaches 145°F and let it rest 10 minutes before slicing. If you overcooked it, try slicing thinner and serving with extra sauce. For future attempts, consider brining the pork for 30 minutes before cooking to keep it juicy.
