Slow Cooker Mushroom Beef Tips

Why Make This Dish?

  • Deep, savory flavor with minimal effort

  • Beef becomes fall-apart tender

  • Makes its own rich gravy in the slow cooker

  • Perfect over rice, noodles, or mashed potatoes


Ingredients

  • 1.5 kg (3 lbs) beef stew meat or sirloin tips, cut into 2-inch cubes

  • 500 g (1 lb) cremini or white mushrooms, sliced

  • 1 large onion, chopped

  • 4 cloves garlic, minced

  • 2 cups beef broth (low sodium preferred)

  • 1 can (10.5 oz / 298 g) cream of mushroom soup (undiluted)

  • 2 tablespoons Worcestershire sauce

  • 1 tablespoon soy sauce (or tamari for gluten-free)

  • 1 teaspoon dried thyme

  • ½ teaspoon black pepper

  • ½ teaspoon salt (adjust to taste)

  • 2 tablespoons cornstarch mixed with 2 tablespoons cold water (slurry, for thickening)

  • 2 tablespoons olive oil (for browning)


Equipment Needed

  • Slow cooker (5–6 quart or larger)

  • Large skillet or Dutch oven

  • Tongs

  • Wooden spoon or spatula

  • Small bowl for slurry


Method

1. Brown the beef (optional but highly recommended)

  • Pat the beef cubes dry with paper towels. This helps them brown instead of steam.

  • Season with a pinch of salt and pepper.

  • Heat olive oil in a large skillet over medium-high heat.

  • Add the beef in a single layer. Do not overcrowd – work in 2–3 batches.

  • Brown for 2–3 minutes per side until deeply golden. Do not cook through.

  • Transfer the browned beef to the slow cooker.

2. Sauté the aromatics

  • Reduce skillet heat to medium.

  • Add the chopped onion to the same skillet. Cook for 3–4 minutes until softened.

  • Add the minced garlic and cook for 1 minute until fragrant.

  • If the skillet looks dry, add a splash of beef broth.

  • Transfer the onions and garlic to the slow cooker.

3. Sauté the mushrooms (optional but recommended)

  • Add the sliced mushrooms to the same skillet.

  • Cook for 5–7 minutes, stirring occasionally, until they release their liquid and start to brown.

  • Transfer the mushrooms to the slow cooker.

4. Make the gravy base

  • In a bowl or directly into the slow cooker, whisk together the beef broth, cream of mushroom soup, Worcestershire sauce, soy sauce, dried thyme, pepper, and salt.

  • Pour over the beef, onions, garlic, and mushrooms. Stir gently to combine.

5. Cook

  • Cover the slow cooker with the lid.

  • Cook on LOW for 7–8 hours, or on HIGH for 4–5 hours.

  • Beef is done when it is fork-tender and easily shreds or cuts with a spoon.

6. Thicken the gravy (optional)

  • In a small bowl, mix the cornstarch with cold water until smooth.

  • Stir the slurry into the slow cooker during the last 30 minutes of cooking.

  • Cover and cook on HIGH until the gravy thickens (about 15–20 minutes).

7. Serve

  • Taste and adjust salt and pepper as needed.

  • Serve hot over egg noodles, white rice, or mashed potatoes.

  • Garnish with fresh parsley if desired.


Serving Suggestions

  • Over wide egg noodles (classic pairing)

  • Over creamy mashed potatoes

  • Over steamed white or brown rice

  • With crusty bread for dipping into the gravy

  • Alongside roasted green beans or a simple green salad


Storage

  • Refrigerator – store in an airtight container for up to 4 days. The flavor improves overnight.

  • Freezer – freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

  • Reheating – warm gently on the stovetop over low heat, adding a splash of beef broth if the gravy is too thick.


Variations

  • Red wine beef tips – add ½ cup dry red wine along with the beef broth for deeper flavor.

  • Garlic lovers – double the garlic to 8 cloves.

  • Herb variation – add 2 sprigs fresh rosemary or 3 sprigs fresh thyme (remove before serving).

  • Onion soup mix version – replace the salt, pepper, and thyme with 1 packet of dry onion soup mix.

  • Vegetable packed – add 2 chopped carrots and 2 chopped celery stalks along with the onions.

  • Gluten-free – use tamari instead of soy sauce and a gluten-free cream of mushroom soup.

  • Instant Pot version – use the sauté function for browning, then pressure cook on HIGH for 35 minutes with a natural release of 15 minutes.


Tips for Best Results

  • Brown the beef properly – deep golden color equals deep flavor. Do not skip or rush this step.

  • Use beef chuck or sirloin tips – these cuts have enough fat and connective tissue to become tender in the slow cooker. Lean cuts like round steak will become dry.

  • Pat the beef dry before browning – moisture prevents browning and creates steam instead of a crust.

  • Do not overcrowd the pan – overcrowding lowers the temperature and causes the beef to steam rather than brown. Work in batches.

  • Sauté the mushrooms – raw mushrooms release too much liquid into the gravy. Sautéing first concentrates their flavor.

  • Use low sodium broth – regular broth plus soy sauce and soup can make the dish too salty. Adjust salt at the end.

  • Thicken at the end – add the cornstarch slurry only during the last 30 minutes. Adding it earlier can break down the gravy.

  • Let it rest before serving – the gravy thickens slightly as it cools for 5–10 minutes.
