Ingredients for pork tenderloin recipe crock pot cream of mushroom
Fourteen ingredients transform into restaurant-quality pork tenderloin with velvety mushroom sauce and crispy celery crowns.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of fat |
| Cream of Mushroom Soup 🍄 | 1 can | Condensed, 10.5 oz can |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Celery Stalks 🧅 | 4 whole | Fresh, trimmed and halved |
| Garlic Cloves 🧄 | 4 cloves | Minced, for searing |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for searing |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening sauce |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Butter 🧈 | 2 tbsp | Unsalted, for celery crowns |
| Panko Breadcrumbs 🍞 | ¼ cup | For crispy celery crowns |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The pork tenderloin is the star—center-cut and trimmed ensures tender results. Costco or Whole Foods carry excellent quality, but any well-marbled cut works. I always sear mine first for extra flavor, using extra-virgin olive oil and minced garlic. The celery? Look for stalks that are crisp and pale green—Trader Joe's has the best selection. Freshness matters here, especially for the celery crowns. The cream of mushroom soup can be any brand, but Campbell's or French's are reliable staples.
No heavy cream? Half-and-half or coconut cream works in a pinch, though the texture won't be quite as rich. The flour is just for thickening—don't skip it, but if you're gluten-free, cornstarch works 1:1. For the celery crowns, the butter and panko combo is non-negotiable for that perfect crunch. Dried thyme is fine, but fresh has a brighter flavor. The parsley is purely for garnish, so dried would work if you're in a bind, but fresh is prettier. Prefer a different herb? Chives or basil would both be delicious.
This dish reheats beautifully—3-5 minutes in the microwave or until piping hot. The celery crowns stay crispy for about 2 days if stored separately, but I always make extra to snack on. The pork and sauce keep for 4-5 days in the fridge, and freezes for 3 months. I double the batch every time—leftovers make amazing sandwiches or tacos. The celery crowns freeze well too, just reheat them in the oven at 375°F for 5 minutes to restore crispiness.

Step-by-Step instructions for creamy crock pot pork tenderloin
This method delivers melt-in-your-mouth pork with a velvety mushroom sauce and crispy celery crowns.
Sear the Pork Tenderloin for Depth of Flavor
Heat a large skillet over medium-high heat and add the 1 tbsp olive oil. Once shimmering, add the 1.5 lb pork tenderloin and sear on all sides for 2-3 minutes per side until golden brown. The high heat creates a flavorful crust while keeping the interior tender.
While the pork sears, season it generously with 1 tsp salt, 0.5 tsp ground black pepper, and 1 tsp dried thyme. I like to press the seasoning into the meat so it adheres well. Once seared to perfection, transfer the pork to your crock pot and set aside.
Prepare the Celery Crowns for Crunchy Garnish
Trim the 4 whole celery stalks by cutting off the leafy tops and bottoms. Then, carefully slice each stalk lengthwise into ¼-inch thick strips, leaving the bottom 1 inch intact to hold them together like a crown. This creates a beautiful presentation and adds texture contrast.
In a small bowl, combine the 0.25 cup panko breadcrumbs with 2 tbsp butter and 1 tbsp all-purpose flour. Toss the celery crowns in this mixture until evenly coated. Spread them out on a baking sheet and set aside for now - we'll crisp them up later.
Build the Creamy Mushroom Sauce Base
In the same skillet you used for searing (no need to clean it), add the 4 cloves minced garlic and sauté for 30 seconds until fragrant. Pour in the 1 can cream of mushroom soup and stir to deglaze the pan, scraping up all those delicious browned bits.
Transfer this sauce mixture to the crock pot along with the seared pork tenderloin. The residual heat will help blend everything together. Then, pour in the 0.5 cup heavy cream and stir gently to combine. The sauce should look silky and inviting at this point.
Slow Cook to Perfect Tenderness
Place the lid on your crock pot and cook on low heat for 4-5 hours or on high heat for 2-3 hours. The pork is done when it reaches an internal temperature of 145°F and is fork-tender. I check for doneness by inserting a meat thermometer into the thickest part of the tenderloin.
During the last 30 minutes of cooking, preheat your oven to 375°F. This will be perfect for crisping up our celery crowns. Remove the pork from the crock pot and let it rest on a cutting board while you prepare the celery.
Finish with Crispy Celery Crowns and Garnish
Arrange the celery crowns on a baking sheet and bake for 8-10 minutes until golden brown and crispy. Watch them closely - they crisp up quickly. While they bake, slice the pork tenderloin into ½-inch thick medallions.
Return the sliced pork to the crock pot with the mushroom sauce and warm through for 2-3 minutes. Spoon the sauce over the pork, garnish with the crispy celery crowns and 0.25 cup chopped fresh parsley. Serve immediately with the rich sauce spooned over the top - each bite delivers tender pork, creamy mushroom sauce, and that satisfying crunch from the celery.
Pro Tips For Making Pork Tenderloin Recipe Crock Pot Cream Of Mushroom
- SEAR THE PORK FIRST: I learned this the hard way—skipping the sear means bland, soggy meat. Hit the tenderloin with a hot pan for 2-3 minutes per side before dumping it in the crock pot. The crust locks in flavor when it braises, and trust me, your guests will notice the difference.
- CHOP THE CELERY SMALL: No one likes to chew through chunks in a creamy sauce. Dice that celery into ¼-inch pieces so it softens evenly and blends into the sauce instead of sitting like a puzzle piece. (Yes, even if you’re impatient like me.)
- LOW AND SLOW WINS: Crank the crock pot to low for 6-7 hours—high heat turns the pork rubbery. The slow cooker’s gentle heat keeps the meat tender while letting the cream of mushroom soup and garlic meld into a rich, velvety finish. No shortcuts here.
- STIR IN THE CREAM LAST: Heavy cream scalds easily, and you don’t want curdled sauce. Add it during the final 30 minutes of cooking, not at the start. If you’re really in a rush, mix a little into the soup first to temper it, then add the rest at the end.
Wine and beer pairings for these flavors
Creamy Sauce Wines
The rich, velvety mushroom sauce pairs beautifully with wines that complement its earthy depth and creamy texture. A Chardonnay from California's Sonoma Coast—like Kendall-Jackson Vintner's Reserve—brings bright acidity and buttery notes that cut through the richness.
The slight oakiness enhances the sauce's creaminess while the citrus undertones balance the mushrooms' earthiness. 🍷
For a lighter option, try a Viognier from Oregon's Willamette Valley. The floral and stone fruit notes in Domaine Serene wines add an elegant contrast to the savory pork, while their natural acidity keeps the meal feeling fresh.
I keep a bottle of this in my fridge for special occasions—it's become a go-to for creamy mushroom dishes.
Bold Red Complements
If you prefer red wine, a Pinot Noir from Oregon's Dundee Hills—like Domaine Serene Pinot Noir—is my top choice. Its red fruit flavors and silky tannins harmonize with the pork's tenderness while standing up to the creamy sauce. The earthy undertones mirror the mushrooms, creating a cohesive flavor experience.
Avoid heavy, tannic reds like Cabernet Sauvignon—they'll overpower the delicate flavors. Instead, opt for a Gamay from Beaujolais if you want something fruit-forward with a touch of spice. The Beaujolais-Villages label guarantees quality at an affordable price.
Beer Pairings
For beer lovers, a Belgian-style Witbier like Hoegaarden offers the perfect balance. The coriander and citrus notes refresh your palate between bites of creamy pork, while the effervescence cleanses the richness. I always keep a six-pack on hand—it's the ultimate crowd-pleaser for this dish.
If you prefer darker beers, try a Belgian Dubbel such as Westmalle Dubbel. The caramel and raisin flavors complement the mushrooms and pork beautifully, while the slight sweetness enhances the sauce's creaminess. For a local Portland option, Breakside Brewery's Dubbel is outstanding.
Non-Alcoholic Options
Don't drink alcohol? No problem. A sparkling apple cider like Martinelli's Sparkling Cider provides the same refreshing contrast as wine or beer. The crisp acidity and fruity notes work wonderfully with the creamy sauce and crispy celery crowns.
For something more sophisticated, try a non-alcoholic Riesling like Freixenet 0.0%. The bright acidity and citrus flavors mimic the characteristics of a traditional wine pairing, making it a surprisingly elegant choice. I've even seen my wine-loving husband reach for this option when entertaining guests.

Frequently asked questions
Can I use boneless pork loin instead of pork tenderloin?
Yes, you can substitute boneless pork loin, but adjust the cooking time. A 1.5 lb pork loin will need about 1-1.5 hours longer on low heat since it has more connective tissue. Trim excess fat first and use a meat thermometer to check for 145°F internal temperature. The sauce ratio stays the same, but the larger cut benefits from a longer slow cook.
What if I don't have panko breadcrumbs for the celery crowns?
No problem! Use crushed cornflakes, crushed potato chips, or even crushed crackers for a different texture. For extra crunch, toast the breadcrumbs in a dry pan for 2-3 minutes before coating the celery. The key is to get that golden, crispy finish—just watch them closely in the oven to avoid burning.
Can I make this recipe without heavy cream?
Swap the 0.5 cup heavy cream with 0.5 cup whole milk + 2 tbsp butter for a lighter version. The sauce will still be creamy, though slightly less rich. For extra depth, add 1 tbsp Dijon mustard to the slow cooker along with the soup. The acidity helps balance the flavors beautifully.
How do I prevent the pork from drying out in the crock pot?
The secret is searing first and keeping the lid on tightly. The high-heat sear creates a flavorful crust, while the slow cooker's moisture keeps the meat tender. For extra insurance, brush the pork with 1 tbsp olive oil before searing. Never skip the 145°F internal temperature check—overcooking is the #1 cause of dryness in slow-cooked pork.
Can I prep this dish ahead of time?
Yes! Prep everything up to Step 3 the night before. Store the seared pork and sauce mixture in the crock pot (uncovered) in the fridge. When ready to cook, add the heavy cream, cover, and slow cook as directed. The celery crowns can be prepped and refrigerated too—just bake them fresh before serving. This makes it perfect for busy weeknights or meal prep Sundays!
