Step‑by‑Step Instructions for Creamy Mushroom & Ground Beef Bake
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). While the oven warms up, take a moment to grease a 9×13-inch baking dish with cooking spray or a little oil to ensure your Creamy Mushroom & Ground Beef Bake doesn’t stick once it’s time to serve.
Step 2: Brown the Beef
In a large skillet, over medium heat, add 1 pound of ground beef. Cook it for about 7-10 minutes, stirring occasionally, until it’s nicely browned and no longer pink. This ensures the meat is flavorful and well-cooked. Once done, carefully drain any excess grease from the skillet.
Step 3: Sauté the Vegetables
Next, add chopped onion to the skillet and sauté for about 3-4 minutes until translucent. Once the onion is softened, toss in minced garlic and sliced mushrooms, cooking everything for an additional 5-6 minutes. The mushrooms should become tender and release their flavorful juices, melding beautifully with the garlic aroma.
Step 4: Combine the Creamy Sauce
Stir in the cream of mushroom soup, ½ cup of either sour cream or heavy cream, and a splash of Worcestershire sauce into the skillet. Season with Italian seasoning, salt, and pepper. Let this mixture simmer on low heat for about 5 minutes, allowing the flavors from the Mushroom & Ground Beef Bake to blend together harmoniously.
Step 5: Mix and Transfer to Baking Dish
In a large bowl, combine the beef mixture with 3 cups of cooked pasta or rice, mixing well to coat everything evenly. Transfer this hearty mixture into the prepared baking dish, spreading it out evenly to ensure all parts of the casserole cook thoroughly.
Step 6: Top with Cheese
Sprinkle your choice of shredded cheese generously over the top of the casserole. This will create a deliciously gooey and bubbly crust as the dish bakes. Make sure to cover the surface evenly for the best melting results in your Creamy Mushroom & Ground Beef Bake.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake uncovered for 20-25 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and lightly golden. The tantalizing aroma wafting through your kitchen will be a clear sign that all is coming together perfectly!
Step 8: Let It Rest
Once baked, remove the dish from the oven and allow it to rest for about 5 minutes before serving. This resting period helps the casserole to set slightly, making it easier to serve those hearty portions of Mushroom & Ground Beef Bake.
Step 9: Garnish and Serve
For a touch of freshness, sprinkle chopped fresh parsley over the top just before serving. This not only adds visual appeal but a vibrant flavor as well. Now, you’re ready to dig in and enjoy this comforting family favorite!
