Round Steak Crock Pot Recipe Cream of Mushroom: Slow-Cooked Savory Richness

Tough cuts transform into melt-in-your-mouth tenderness with this slow-cooker method. I developed this recipe after years of testing in my tiny Boston kitchen, finding the perfect balance of time and ingredients.

The secret is low and slow cooking with cream of mushroom soup, which breaks down the meat while creating a rich, velvety gravy. Round steak, often overlooked, becomes the star of this hearty dish.

What emerges after 6-8 hours is fork-tender beef in a savory sauce that soaks into every bite. The mushrooms add earthy depth, while the slow cooker does all the work.

Perfect for Sunday suppers or busy weeknights. This is comfort food at its most reliable.

Ingredients for Round Steak Crock Pot Recipe Cream of Mushroom

Round steak, cream of mushroom soup, and a few pantry staples create this slow-cooked masterpiece.

Round steak is the star here. Look for well-marbled cuts at Whole Foods or your local butcher—avoid anything labeled ‘lean’ since the fat keeps it tender. The cream of mushroom soup should be Campbell’s or a trusted brand; generic versions can be watery. I always grab my mushrooms fresh from the produce section (pre-sliced saves time but whole mushrooms stay fresher longer).

No round steak? Chuck roast cut into strips works just as well. For a creamier texture, swap one can of mushroom soup for cream of celery. If you’re out of fresh mushrooms, canned mushrooms at half the amount will do. The Worcestershire sauce is key for depth—Annie’s or Lea & Perrins are solid choices. No Dijon? Regular yellow mustard works in a pinch.

This dish tastes even better the next day. Store leftovers in an airtight container for up to 4 days in the fridge or freeze for 3 months. The gravy thickens as it cools, so thin with a splash of broth when reheating.

Step-by-Step Instructions for Round Steak Crock Pot Cream of Mushroom

Here is the method. Straightforward, tested, works every time.

Step 1: Sear and Season the Round Steak

Cut the 1.5 lb Round Steak into 1-inch strips as specified. Pat them dry with paper towels to ensure a good sear. Season both sides generously with the 1 tsp Salt and 0.5 tsp Black Pepper.

Heat the 2 tbsp Olive Oil in a large skillet over medium-high heat until shimmering. Working in batches to avoid crowding, sear the steak strips for 2-3 minutes per side until browned. This step locks in flavor and creates a rich fond for the sauce. Transfer the seared steak to your crock pot.

Step 2: Sauté the Aromatics

In the same skillet, add the sliced 1 whole Onion and 8 oz Mushrooms. Sauté over medium heat for 5-6 minutes until the onions soften and the mushrooms release their moisture. Stir in the minced 3 cloves Garlic Cloves and cook for an additional 30 seconds until fragrant.

Sprinkle the 0.25 cup All-Purpose Flour over the vegetables and stir to coat. Cook for 1-2 minutes to remove the raw flour taste. This creates a roux that will thicken your sauce beautifully.

Step 3: Build the Sauce and Slow Cook

Add the 2 cans Cream of Mushroom Soup, 0.5 cup Beef Broth, 1 tbsp Worcestershire Sauce, 1 tbsp Dijon Mustard, 1 tsp Dried Thyme, and 1 tsp Dried Rosemary to the skillet. Stir well, scraping up any browned bits from the bottom. Pour this mixture over the steak in the crock pot.

Stir everything together to ensure the steak is fully coated. Cover and cook on low heat for 6-7 hours or on high heat for 3-4 hours. The dish is done when the steak is fork-tender and the sauce has thickened to your liking.

Step 4: Adjust and Serve

Taste and adjust seasoning if needed. The sauce should be rich and velvety, coating the back of a spoon. If it’s too thick, stir in a splash of additional beef broth.

Serve the steak and sauce hot over mashed potatoes, egg noodles, or rice. The slow cooking ensures the round steak becomes tender and absorbs all the savory flavors from the cream of mushroom sauce. This dish tastes even better the next day as the flavors meld together.

Accurate measurements matter, especially for the flour and spices. I keep a set of OXO Good Grips measuring cups and spoons handy. The magnetic backs keep them organized in my limited drawer space. For the broth, a 1-cup Pyrex measuring cup does double duty.

Wooden Spoons

When building your sauce in the skillet, use a wooden spoon to scrape up those flavorful browned bits. I prefer bamboo spoons—they’re gentle on my cookware and won’t melt or warp. Plus, they’re easy to find at any regular grocery store in Boston.

For easy cleanup, I always use Reynolds Slow Cooker Liners. They save so much time after dinner when I’m ready to relax. Just line your crock, cook as usual, and toss the liner when you’re done. No more scrubbing baked-on sauce from the pot. ✨
