Ingredients for pork tenderloin recipe crock pot cream of mushroom
Simple ingredients that transform into a luxurious crock pot pork tenderloin with velvety mushroom sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Trimmed of fat and silver skin |
| Fresh White Mushrooms 🍄 | 16 oz | Sliced into thin strips |
| Heavy Cream 🥛 | 1 cup | Full-fat for velvety texture |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic base |
| Shallot 🧅 | 1 whole | Minced for subtle sweetness |
| Dry White Wine 🍷 | ½ cup | Substitute with broth if needed |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Thyme 🌿 | 1 tsp | Dried or 1 tbsp fresh |
| Butter 🧈 | 2 tbsp | Unsalted for flavor control |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
The pork tenderloin is the star here—look for one that's uniform in size (about 1.5 lbs) for even cooking. Costco or local butchers usually have great options, often pre-trimmed for convenience. If yours has fat or silver skin, trim it first—it keeps the meat tender but can make the sauce greasy. The mushrooms should be firm and white (no brown spots), and fresh is ideal, but pre-sliced from the store works too. For the wine, any dry white like Sauvignon Blanc or Pinot Grigio adds brightness, but skip it if you prefer—just boost the broth by a splash.
No white wine? Extra chicken broth keeps the sauce rich. Fresh thyme is ideal, but dried at one-third the amount works fine. The shallot can be swapped for 2 tbsp minced onion if needed. For the sauce to thicken properly, make sure to whisk the flour into the cold cream before adding to the pot—this prevents lumps. If your mushrooms release a lot of water, drain them briefly before adding to avoid a watery sauce. The butter at the end adds richness, but you can use olive oil if preferred—just reduce the amount slightly.
This dish reheats beautifully—simmer on low for 10 minutes to restore creaminess. Store in airtight containers for 3-4 days in the fridge or 3 months frozen. I always make extra sauce to drizzle over mashed potatoes or roasted veggies—it’s that good. The pork stays juicy for days, so you can prep ahead and just reheat when ready. Garnish with parsley right before serving, as it wilts quickly in the warm sauce.

The slow cooker does all the work while you sip wine or fold laundry.

Step-by-step instructions for pork tenderloin in cream of mushroom sauce
Here's how to turn simple ingredients into melt-in-your-mouth pork with a velvety mushroom sauce.
Prepare the Pork and Sear for Flavor
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this ensures a perfect sear. Season all sides generously with 1 tsp salt, 0.5 tsp black pepper, and 1 tsp thyme. Let it sit at room temperature for 15 minutes while you prep everything else.
Heat a large skillet over medium-high heat and add 2 tbsp butter. Once the butter foams, add the pork and sear for 2-3 minutes per side until golden brown. You'll see those beautiful crusty spots—this builds flavor that carries through the slow cook. Transfer the seared pork to your crock pot and set aside.
Build the Sauce Base with Aromatics
In the same skillet (no need to clean it—the browned bits add flavor), add 1 whole minced shallot and 4 minced garlic cloves. Sauté for 1-2 minutes until fragrant but not browned. Here's the thing—if you let the garlic brown, it'll turn bitter, so keep an eye on it.
Pour in 0.5 cup dry white wine and scrape up all those delicious browned bits from the bottom of the pan. Let it simmer for 2-3 minutes until reduced by half. This deglazing step captures all that meaty flavor that would otherwise stick to your pan.
Combine Ingredients and Slow Cook
Add the 16 oz sliced fresh white mushrooms, 1 cup chicken broth, and 2 tbsp all-purpose flour to the crock pot with the pork. Stir gently to combine, then pour in the wine mixture from the skillet. The flour will help thicken the sauce later, but don't worry—it'll dissolve completely during cooking.
Cook on LOW for 4-5 hours or HIGH for 2-3 hours, until the pork reaches an internal temperature of 145°F and is fork-tender. The sauce should thicken beautifully during this time, creating that luxurious cream of mushroom consistency we're after.
Finish with Cream and Garnish
Once the pork is cooked, carefully remove it from the crock pot and set aside to rest. Stir 1 cup heavy cream into the sauce in the crock pot and cook on HIGH for 15-20 minutes until the sauce is thick and creamy. If it's too thick, you can thin it with a splash of broth.
Slice the pork into ½-inch thick medallions and serve it smothered in that velvety mushroom sauce. Garnish with 0.25 cup chopped fresh parsley for a pop of color and freshness. Each bite should deliver perfectly tender pork with a rich, creamy sauce that coats every forkful.
Pro Tips For Making Pork Tenderloin Recipe Crock Pot Cream Of Mushroom
- Pat the pork dry: I learned this the hard way—wet pork steams instead of searing. Grab a paper towel and really dry the tenderloin before searing; it’ll give you a golden crust that keeps the meat juicy, not soggy, even after hours in the crock pot.
- Sear before slow-cooking: Skip the "just throw it in" approach. Sear the pork tenderloin in a hot skillet for 2-3 minutes per side first—it adds depth to the flavor that crock-pot cooking alone can’t match. (Yes, even if you’re impatient like me.)
- Sauté mushrooms first: Fresh mushrooms release their water like crazy in the crock pot. Sauté them in butter or oil until they’re deeply browned and most of the liquid’s evaporated before adding them to the pot. This keeps your sauce thick and rich, not watery.
- Use cornstarch, not flour: Flour can make the sauce gummy. After the pork cooks, mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir it into the sauce, and let it thicken on the stovetop for 2-3 minutes. It’s the non-negotiable step that turns a good sauce into a great one.
Flavor customization for these flavors
Spicy Mushroom Twist
Add 1 tbsp Penzeys smoked paprika and ½ tsp cayenne pepper to the crock pot when combining ingredients. For extra depth, stir in 1 tsp fish sauce after the pork cooks—it balances heat beautifully.
I first tried this after a Thai street food night in Portland, and it became an instant favorite. The smoky-sweet contrast with the creamy sauce is pure magic. 🌶️
Herb-Infused Variations
Swap thyme for 1 tbsp fresh rosemary and 1 tsp fresh tarragon for a French bistro vibe. Or try ½ tsp ground nutmeg and 1 tsp fresh sage for a cozy Thanksgiving feel.
Fresh herbs should be added at the very end—just before serving—to keep their brightness. I keep dried herbs on hand for convenience, but fresh always tastes better.
Creamy Cheese Boost
Stir in ½ cup grated Gruyère or Parmesan cheese with the heavy cream during the final 15 minutes of cooking. The cheese melts into the sauce, adding nutty richness.
For a vegetarian option, omit the pork and use 1.5 lbs extra-firm tofu pressed and pan-seared first. The sauce clings perfectly to both proteins. 🧀
Umami Bomb Additions
Boost the sauce with 1 tbsp soy sauce or 1 tsp miso paste when adding the wine mixture. For deeper flavor, add 2 slices bacon cooked crispy and crumbled into the crock pot.
I love this combo—it adds smoky, salty layers that make the sauce even more complex. Store-bought bacon works, but local butchers often have better-quality options.
Sweet Glaze Option
For a sweet-savory twist, add 2 tbsp apricot jam or 1 tbsp honey to the sauce during the final 10 minutes of cooking. This works especially well with the spicy variation, balancing the heat.
I discovered this trick while making pork tenderloin for my daughter Lily's birthday—she loved the sweet-tangy sauce. 🍯
Vegetarian Adaptation
Replace the pork with 1.5 lbs king oyster mushrooms or hearts of palm** for a meaty texture. Sear them first in butter just like the pork, then proceed with the recipe.
The mushrooms absorb the sauce beautifully, creating a hearty vegetarian main dish. I've tested this with both ingredients, and the king oyster mushrooms hold up best to the creamy sauce. 🍄

Frequently asked questions
Can I use boneless pork chops instead of pork tenderloin?
You can try, but the cooking time and texture will differ. Pork chops need about 2-3 hours on HIGH or 4-5 hours on LOW and may stay slightly firmer. For best results, use 1.5-inch thick chops and check for 145°F internal temp. The sauce will still work perfectly, but the meat won't be as tender as tenderloin.
How do I fix a watery sauce? If your sauce turns out too thin, mix 1 tbsp cornstarch with 2 tbsp cold water and stir it into the simmering sauce. Cook for 2-3 minutes until thickened. For prevention,
What's the best way to reheat leftovers?
Reheat in the crock pot on LOW for 1-2 hours or in a saucepan over medium-low heat until warmed through. Add a splash of broth or water if the sauce seems too thick. The pork stays juicy when reheated gently—never microwave it directly, as it can dry out.
Can I make this ahead for a dinner party?
Cook the pork and sauce completely, then refrigerate in an airtight container. Reheat on LOW for 2 hours before serving. For extra flavor, add fresh parsley and a pat of butter just before serving. This method lets you enjoy your guests without last-minute stress.
What if I don't have white wine?
No problem! Substitute with ½ cup extra chicken broth or apple cider vinegar (just 1 tbsp) for acidity. The sauce will still develop rich flavor—just reduce the broth by half before adding it to the crock pot. The vinegar adds a subtle tang that works beautifully with the mushrooms.
