Ingredients

• 2 pounds beef stew meat, cut into bite-sized pieces
• 1 can (10.5 ounces) condensed cream of mushroom soup
• 1 cup beef broth
• 1 medium yellow onion, thinly sliced

These four ingredients work together to create a flavorful beef bake with a creamy mushroom gravy. Beef chuck stew meat is a good choice because it becomes tender during slow, moist cooking.

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 325°F. Choose a deep casserole dish with a tight-fitting lid. If your dish does not have a lid, use aluminum foil to cover it securely.

Step 2: Arrange the Beef and Onion

Place the beef stew meat in the casserole dish and spread the sliced onion over the top. Distribute the pieces evenly so the beef cooks consistently.

Step 3: Prepare the Creamy Mushroom Sauce

In a medium bowl, whisk together the condensed cream of mushroom soup and beef broth until smooth. Pour the mixture over the beef and onions, stirring gently to coat the meat.

The sauce may look thick before baking, but the beef will release juices as it cooks, helping create a rich gravy.

Step 4: Cover and Bake

Cover the dish tightly and bake for approximately 2½ to 3½ hours, checking near the end of the cooking time. The beef should be fork-tender, and the onions should be soft.

If the beef is still tough, cover the dish again and continue baking in 20- to 30-minute increments. Tougher cuts need enough time for their connective tissue to soften. If the sauce becomes too thick, add a small splash of hot broth or water.

Step 5: Rest and Serve

Remove the casserole from the oven and let it rest for about 10 minutes. Stir the sauce gently, then spoon the creamy beef mixture over your preferred side dish.

Tips for the Best Creamy Mushroom Beef Bake

• Use stew meat suitable for braising: Beef chuck is particularly good for long, slow cooking.
• Keep the dish covered: This helps retain moisture and prevents the sauce from reducing too quickly.
• Allow enough cooking time: Beef is ready when it is fork-tender, not merely when it reaches a minimum safe temperature.
• Stir before serving: This distributes the softened onions and creamy gravy evenly.
• Avoid adding too much liquid: Start with the listed amount of broth and adjust only if the sauce becomes overly thick.

What to Serve with Creamy Mushroom Beef

This beef bake is delicious served over creamy mashed potatoes, egg noodles, white rice, or buttered pasta. Steamed green beans, peas, or roasted carrots make excellent vegetable sides.

For a simple comfort-food dinner, serve it with warm dinner rolls to soak up the mushroom gravy.

Storage and Reheating

Refrigerate leftovers in a shallow, airtight container within two hours of cooking. Store for 3–4 days. Reheat on the stovetop over medium-low heat or in the microwave until the beef and sauce reach 165°F, stirring as needed. Add a small splash of broth if the sauce thickens during storage.

For longer storage, freeze cooled portions in airtight freezer-safe containers for up to three months for best quality. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use a different cut of beef?

Yes. Beef chuck or other cuts sold for stewing work well because they become tender during slow, moist cooking.

Can I prepare this recipe ahead of time?

You can slice the onion and mix the sauce ahead of time, keeping everything refrigerated separately until you're ready to assemble and bake.

Why is my beef still tough after baking?

The meat likely needs more time. Keep the casserole covered and continue baking until a fork slides into the beef easily.
