Step‑by‑Step Instructions for Ground Beef Casserole
Step 1: Prepare Ingredients
Begin by dicing the onion and mincing the garlic as you preheat your oven to 350°F (175°C). Gather your mixed vegetables and cream of mushroom soup, ensuring everything is ready for a smooth cooking process. Having your ingredients prepped will streamline the assembly of your delicious Ground Beef Casserole.
Step 2: Cook Beef
In a large skillet over medium heat, add the ground beef, breaking it apart as it cooks. Sauté for about 5-7 minutes until browned. You’ll know it’s done when the meat is no longer pink and starts to caramelize. Once cooked, drain any excess fat to keep your casserole healthy and flavorful.
Step 3: Add Aromatics
Stir the diced onion and minced garlic into the skillet with the beef and sauté for 2-3 minutes. Keep an eye on them—the onions should become translucent and aromatic, infusing your Ground Beef Casserole with delightful flavors. This step builds the foundation of your hearty dish.
Step 4: Mix in Vegetables
Add the mixed vegetables to the skillet, stirring them in for an additional 2 minutes. If using frozen vegetables, you’ll want to see them thaw and brighten in color. This not only enhances the nutritional value but also adds a beautiful array of colors to your casserole.
Step 5: Combine with Sauce
Pour in the cream of mushroom soup, thoroughly mixing it with the beef and vegetable blend. Make sure every ingredient is evenly coated with the creamy goodness. This is what makes your Ground Beef Casserole rich and comforting, all while bringing everything together beautifully.
Step 6: Transfer to Baking Dish
Carefully spread the mixture evenly into a greased casserole dish. Using a spatula helps keep everything uniform. This ensures even cooking and allows every bite of your Ground Beef Casserole to be just as delicious as the last.
Step 7: Top with Cheese and Bread Crumbs
Sprinkle a generous layer of shredded cheese over the top of your casserole, followed by optional breadcrumbs or crushed crackers for that extra crunch. This topping will melt and create a golden, irresistible finish, enhancing the overall appeal of your dish.
Step 8: Bake
Place the baking dish in the preheated oven and bake for 30-40 minutes. You’ll know it’s ready when the cheese is bubbly and golden brown. The tempting aroma filling your kitchen will let you know you’re in for a hearty treat with this comforting Ground Beef Casserole.
Step 9: Cool and Serve
After baking, let the casserole sit for 5-10 minutes before serving. This resting time allows for easier portioning and enhances the flavors even more. Slice into your warm Ground Beef Casserole, and get ready to share a delightful meal with your family!
