Pork Loin and Cream of Mushroom Soup Recipe: One-Pan Creamy Comfort with Golden Crust

This pork loin and cream of mushroom soup recipe delivers the ultimate one-pan comfort meal—tender, golden pork paired with velvety mushroom sauce that feels like a restaurant favorite.

I developed this during a particularly chilly Atlanta winter when I needed a dish that combined protein and sauce in one effortless package. The secret lies in searing the pork first to create that perfect crust, then finishing it in the oven while the soup simmers below.

The homemade cream of mushroom soup starts with sautéed mushrooms and onions, then blends into a rich, velvety sauce using cream and chicken broth. What makes this recipe special is how the pork and soup cook together—infusing the sauce with porky depth while keeping the meat impossibly tender.

No need for separate pans or complicated techniques; just one skillet, one oven, and about an hour of hands-off cooking.

By the time you serve it, you'll have perfectly golden pork loin with crisp edges and juicy centers, all nestled in a creamy mushroom sauce that's rich but not heavy.

The aroma alone will have everyone gathering at the table, and the combination of textures—tender meat, velvety sauce, and crisp edges—makes every bite satisfying. This is the kind of meal that turns a regular weeknight into a cozy dinner experience.

Pair it with mashed potatoes or steamed green beans for a complete meal, or serve it over buttered egg noodles for a heartier option. The leftovers reheat beautifully too—just add a splash of broth or cream to restore that creamy texture. Let's get cooking!

Ingredients for pork loin and cream of mushroom soup

Golden pork and velvety mushrooms—just 14 ingredients for restaurant-style comfort.

The pork loin is non-negotiable here—center-cut stays juicier than regular cuts. Grab one from the butcher counter if you can, or the pre-trimmed ones at Costco work perfectly. Look for good marbling, not too lean. The mushrooms? White buttons are classic, but cremini or baby bella add earthier flavor. For the broth, Swanson or Pacific Foods are my go-tos—they're low-sodium and reliable. Fresh thyme is ideal, but dried works in a pinch (just use one-third the amount).

No Dijon mustard? Yellow mustard at half the amount gets you close. Short on chicken broth? Vegetable broth works, though it'll lack that meaty depth. The flour for dredging? King Arthur or Bob's Red Mill are my favorites—they're fine enough for a good crust without being too heavy. For a dairy-free version, swap the heavy cream for coconut cream (it's richer than regular coconut milk). The Worcestershire sauce adds that savory punch—Lea & Perrins is the classic choice, but any brand will do.

This dish reheats beautifully—just add a splash of broth or cream to restore that creamy texture. Store leftovers in the fridge for 3-4 days or freeze for up to 3 months. I always make a double batch because it's that good. The pork stays juicy when reheated, and the sauce thickens up nicely. For serving, I like it over buttered egg noodles or with a side of garlic mashed potatoes—both soak up that creamy goodness.

Step-by-step instructions for pork loin with cream of mushroom soup

Here's how to create a rich, velvety soup with perfectly seared pork and tender mushrooms.

Pat the 1.5 lb boneless pork loin dry with paper towels—this ensures a golden crust. Season both sides generously with 1.5 tsp salt and 0.5 tsp ground black pepper. Heat 2 tbsp unsalted butter in a large oven-safe skillet over medium-high heat until foaming. Add the pork and sear for 3-4 minutes per side until deeply browned and the internal temperature reaches 145°F on a meat thermometer.

Here's the thing—don't rush this step. The crust forms that rich, caramelized flavor that carries through the soup. If the butter starts to smoke excessively, reduce heat slightly. Once seared, remove the pork and set it aside on a plate.

In the same skillet (no need to clean it—the browned bits add flavor), add 1 whole yellow onion and 16 oz white button mushrooms, sliced into ¼-inch pieces. Cook for 5-6 minutes until the mushrooms release their moisture and begin to soften. Add 4 cloves minced garlic and cook for 30 seconds until fragrant—don't let it burn.

Stir in 1 tbsp Dijon mustard and 1 tsp Worcestershire sauce, scraping up any browned bits from the bottom. This step develops the umami depth that makes this soup so satisfying. If the mushrooms seem dry, add 2 tbsp chicken broth to deglaze the pan and keep everything moist.

Sprinkle 1 tbsp all-purpose flour over the mushroom mixture and stir to coat evenly. Pour in 2 cups chicken broth and bring to a gentle simmer. Let it cook for 5 minutes until slightly thickened. Then, stir in 1 cup heavy cream and 0.25 cup chopped fresh thyme leaves, reducing heat to medium-low. Simmer for another 3-4 minutes until the sauce reaches your desired creaminess.

This is where the magic happens—the cream and broth blend into a luxurious texture. Taste and adjust seasoning if needed, adding more salt or pepper as necessary. The sauce should coat the back of a spoon but still be smooth, not gluey.

Return the seared pork loin to the skillet, spooning some of the mushroom sauce over the top. Cover and transfer to a 375°F preheated oven. Bake for 20-25 minutes until the pork reaches an internal temperature of 150°F. Remove from oven and let rest for 10 minutes before slicing.

This resting period is crucial—it allows the juices to redistribute, ensuring each slice stays moist. While it rests, you can slice the pork against the grain into ½-inch thick pieces and return them to the skillet to absorb any remaining sauce.

Essential equipment for this dish

Oven-Safe Skillet

An oven-safe skillet is non-negotiable for this recipe—it needs to handle both stovetop searing and oven finishing. I swear by All-Clad Stainless Steel or Lodge Cast Iron skillets (12-inch diameter). The Lodge's heavy gauge holds heat beautifully, while All-Clad's stainless surface prevents sticking.

If you don't have either, a Le Creuset Dutch oven works perfectly too. Just make sure it's rated for oven use up to 400°F. 🔥

Meat Thermometer

Never guess pork doneness—use a digital instant-read thermometer like the ThermoWorks Thermapen. It's my go-to for precision, but even a basic Taylor Precision model works.

You'll need it to hit 145°F during searing and 150°F after baking. Pro tip: I keep mine on my countertop for quick checks during cooking.

Sharp Chef's Knife

A sharp 8-inch chef's knife is essential for slicing the pork loin against the grain. My favorite is the Wüsthof Classic—it stays sharp for years. For mushrooms, a slicing motion (not chopping) gives you even ¼-inch pieces.

If your knife is dull, take 10 minutes to hone it with a Whetstone before starting. Trust me, this makes all the difference in texture.

Whisk for Smooth Sauce

For that velvety cream of mushroom sauce, a balloon whisk is your best friend. I use a OXO Good Grips—it's lightweight but sturdy. Whisking the flour into the mushrooms first creates a smooth roux without lumps.

If you don't have one, a fork works in a pinch, but you'll need to stir more vigorously. The goal is to eliminate any graininess in the final sauce.

Fine-Mesh Strainer

If you prefer a smoother sauce without mushroom chunks, a fine-mesh strainer (like the OXO Good Grips) lets you strain the cooked mushrooms before blending. I don't always do this—sometimes I like texture—but it's handy when serving kids or guests who prefer ultra-smooth soups.

Just press the mushrooms with a spoon to extract all the flavorful liquid. 💫
