Ingredients for pork tenderloin recipe crock pot cream of mushroom
Pantry staples plus a few fresh ingredients create this restaurant-quality crock pot pork tenderloin.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Trimmed of fat, even thickness |
| Cream of Mushroom Soup 🍄 | 1 can | Condensed, quality brand preferred |
| White Button Mushrooms 🍄 | 8 oz | Sliced, fresh or frozen |
| Celery Stalks 🧅 | 2 whole | Diced for sauce and crown |
| Garlic Cloves 🧄 | 3 cloves | Minced for flavor depth |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Yellow Onion 🧅 | ½ cup | Diced, medium size |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme |
| Butter 🧈 | 2 tbsp | Unsalted, for celery crown |
| Panko Breadcrumbs 🍞 | ¼ cup | For crispy celery crown |
The pork tenderloin is the star here—look for one with even thickness (about 1.5 inches) for consistent cooking. Costco or local butchers usually have good quality, but the regular supermarket works too. Trim any visible fat before cooking—it keeps the sauce lighter. For the mushrooms, fresh white buttons are ideal, but frozen works in a pinch. The celery crown needs crisp stalks—avoid wilted or rubbery pieces. Prep everything before starting the crock pot; this recipe is all about hands-off ease once you begin.
No cream of mushroom soup? Combine 1 cup chicken broth with 2 tbsp tomato paste and 1 tbsp flour for a quick substitute. Swap heavy cream for coconut milk if needed, though the texture will be slightly lighter. Fresh thyme is better, but dried works at half the amount. The celery crown can be made ahead—just store the uncooked pieces in a sealed bag in the fridge for up to 2 days. If you can't find panko, regular breadcrumbs toasted in the oven work fine. The sauce thickens as it cooks, so don't worry if it looks thin at first.
This dish reheats beautifully—add a splash of broth or water if the sauce thickens too much when warming. Store leftovers in the fridge for 4-5 days or freeze for 3 months. The celery crown stays crispy for about 1 day if refrigerated in an airtight container. Double the recipe if you're feeding a crowd—it's that good. I always make extra sauce to serve on the side; it's perfect for dipping roasted veggies or crusty bread.

Step-by-step instructions for pork tenderloin crock pot cream of mushroom
Here's how to create melt-in-your-mouth pork with a crispy celery crown and rich mushroom sauce.
Prepare the Pork and Celery Crown
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this helps create a better sear later. Season generously with 1 tsp salt, 0.5 tsp black pepper, and 0.5 tsp dried thyme. For the celery crown, cut 1 whole celery stalk into ½-inch thick slices and set aside.
In a small bowl, mix the remaining 1 whole celery stalk (diced), 0.5 cup yellow onion (diced), and 3 cloves garlic cloves (minced). Melt 2 tbsp butter in a skillet over medium heat and sauté the celery-onion mixture for 3-4 minutes until softened but not browned. This aromatic base will form the flavor foundation for your sauce.
Sear the Pork and Build the Sauce Base
Heat a large skillet over medium-high heat and add the seasoned pork tenderloin. Sear for 2-3 minutes per side until golden brown—this step creates a flavorful crust that won't dissolve in the slow cooker. Transfer the seared pork to your 6-quart slow cooker.
To the same skillet, add 2 tbsp all-purpose flour and whisk constantly for 1 minute until bubbly and golden. Immediately pour in 1 cup chicken broth and scrape up any browned bits from the bottom (this is called deglazing). Pour this mixture into the slow cooker along with 1 can cream of mushroom soup and 8 oz sliced white button mushrooms.
Slow Cook to Perfect Tenderness
Place the slow cooker on low heat and cook uncovered for 6-7 hours. The pork is done when it reaches an internal temperature of 145°F and feels tender when pressed with a fork. Here's the thing—don't peek or stir during cooking. Every time you open the lid, you lose heat and moisture that should be working to break down the meat.
About 30 minutes before serving, stir in the 0.5 cup heavy cream and the sautéed celery crown pieces. The cream will blend into the sauce while the celery crown will soak up some of the rich flavors. The sauce should be thick and velvety, coating the back of a spoon when you test it.
Crisp the Celery Crown and Serve
While the pork finishes cooking, heat a skillet over medium heat. Add the celery crown slices and cook for 2-3 minutes per side until golden brown. In a small bowl, mix 0.25 cup panko breadcrumbs with 1 tbsp melted butter and ¼ tsp salt. Toss the crisped celery crown in this mixture and return to the skillet for 1 minute to toast the breadcrumbs.
Remove the pork from the slow cooker and let it rest for 5-10 minutes before slicing. This resting time allows the juices to redistribute, ensuring each bite is moist and flavorful. Serve the sliced pork over a bed of the creamy mushroom sauce, topped with the crispy celery crown. The contrast of textures and temperatures makes this dish truly special—creamy, tender pork with a satisfying crunch from the celery crown.
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 flavorless pork swimming in soup. Hit a hot pan with oil, get that meat golden on all sides before it even touches the crock pot. The contrast in textures and flavors makes a real difference.
- CHOP MUSHROOMS UNIFORMLY: Small, even pieces cook faster and blend better into the sauce. I used to toss in random chunks, and they’d turn to mush while the celery stayed crunchy. Aim for ½-inch dice—consistency is everything.
- DON’T OVERFILL THE CROCK: That soup expands, and you’ll end up with a watery mess. Fill the pot only halfway—pork, veggies, and soup should sit comfortably with room to spare. Trust me, your sauce won’t disappoint.
- SAUTÉ VEGETABLES BEFORE ADDING: Raw celery and garlic just sit there, stealing heat and flavor. Quickly cook them in the same pan you seared the pork until fragrant—about 3 minutes—before dumping everything into the crock. It’s the thing that matters most for depth.
Troubleshooting perfect results
Sauce Too Thin?
If your sauce ends up thinner than expected, don't panic—this is an easy fix. About 30 minutes before serving, remove the pork tenderloin and place it in a clean bowl.
Stir 1 tbsp cornstarch mixed with 2 tbsp cold water into the sauce and let it simmer on the stove over medium heat for 5-7 minutes until it thickens. Return the pork to the slow cooker and warm through.
I've done this trick countless times, especially when I forget to account for the extra moisture from the mushrooms. 💡
Pork Not Tender Enough
The most common reason pork comes out tough is cooking it at too high a temperature or not long enough. Always use low heat for 6-7 hours—this is non-negotiable for tender results.
If your pork still feels firm, transfer it to a baking dish, cover with foil, and bake at 325°F for an additional 30-45 minutes. A meat thermometer is your best friend here—aim for 145°F internal temperature.
I learned this lesson the hard way with my first crock pot pork attempt!
Celery Crown Too Soft
For a perfectly crispy celery crown, timing and temperature are everything. Cook the celery slices in the skillet over medium heat until golden brown—don't rush this step. The secret is to remove them just as they start to crisp, then immediately toss with the panko mixture.
If they end up soggy, try cooking them again in a dry skillet for 1-2 minutes to restore the crunch. I keep a stash of extra panko in my pantry just for emergencies like this! 🧅
Sauce Separates or Curdles
This usually happens when the sauce gets too hot too quickly, especially when adding the heavy cream. To prevent this, always stir the cream in gently and keep the heat on low. If it does separate, whisk in 1 tbsp cold butter and warm the sauce gently until smooth.
The key is patience—don't let the sauce boil. I once ruined a batch by being too eager to serve, but now I always let the cream warm slowly. 🥛
Overpowering Mushroom Flavor
If the mushroom flavor dominates the dish, balance it by adding more acidity. Stir in 1 tsp lemon juice or ½ tsp apple cider vinegar to brighten the sauce. Fresh herbs like parsley or thyme can also help lift the flavors.
I keep a small bottle of vinegar in my fridge specifically for this purpose—it's saved me more times than I can count! 🌿
Slow Cooker Overflows
This is a common issue with rich sauces, especially when the cream is added. To prevent overflow, reduce the liquid slightly by simmering the sauce uncovered for 10-15 minutes on the stove before adding it back to the slow cooker.
Another trick is to add the cream just 30 minutes before serving so it has less time to release steam. I've had to bail out sauces with a spoon before—it's not pretty, but it works! ⚡

Frequently asked questions
Can I use pork loin instead of pork tenderloin?
While pork loin works, it's not ideal because the cooking time and tenderness differ. Pork loin has more fat and connective tissue that needs longer cooking, while tenderloin cooks quickly in a crock pot. If you must substitute, use a 1.5 lb pork loin and cook on low for 8 hours instead of 6-7. The sauce will still work, but the texture may be slightly different.
What if I don't have cream of mushroom soup?
No problem! Mix 1 cup chicken broth with 2 tbsp tomato paste and 1 tbsp flour for a quick substitute. For extra depth, add 1 tsp Worcestershire sauce or a pinch of nutmeg. The flavor won't be identical, but it'll still create a delicious, creamy base for your dish.
How do I make this recipe in a smaller crock pot?
Reduce the recipe by half—use 0.75 lb pork tenderloin, ½ can cream of mushroom soup, and adjust other ingredients proportionally. Cook on low for 4-5 hours instead of 6-7. The sauce will still be rich, but you may need to add a splash of broth if it seems too thick. A 3-4 quart crock pot works perfectly for this scaled-down version.
Can I prepare this ahead of time?
Cook the pork and sauce as directed, then let it cool completely. Store in an airtight container in the fridge for up to 4 days. Reheat on low for 2 hours or until warmed through. The celery crown should be made fresh before serving to maintain its crispiness. This makes it perfect for meal prep—just assemble and serve when ready.
What are the best sides for this dish?
This rich, creamy pork pairs beautifully with lighter sides like roasted asparagus, mashed cauliflower, or a fresh green salad. For heartier options, try garlic roasted potatoes, crusty bread, or steamed green beans. The celery crown's crunch contrasts perfectly with soft textures. I love serving it with a simple arugula salad dressed with lemon vinaigrette to cut through the richness.
