This Cheesy Beef & Vegetable Casserole is a comforting, family-style dinner packed with savory ground beef, tender vegetables, and melty cheddar cheese — baked until bubbling and golden.
1 lb ground beef (85% lean)
1 small onion, finely chopped
2 cloves garlic, minced
2 cups frozen mixed vegetables
1 can (10.5 oz) cream of mushroom soup
1/2 cup milk or beef broth
1 1/2 cups shredded cheddar cheese
1/2 tsp salt
1/2 tsp black pepper
1/2 tsp dried thyme
1/2 tsp smoked paprika
2 cups cooked pasta or diced potatoes (optional)
1/3 cup breadcrumbs or crushed crackers (optional)
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Brown ground beef in a skillet over medium heat. Drain excess fat.
Add onion and garlic; sauté until soft.
Stir in vegetables and seasonings. Cook for 3–4 minutes.
Mix soup and milk in a bowl, then add to the skillet. Stir to coat.
Fold in pasta or potatoes if using. Transfer mixture to baking dish.
Top with shredded cheese and optional breadcrumbs.
Bake uncovered for 25–30 minutes, until bubbly and golden.
Let rest for 5–10 minutes before serving.
Make ahead and refrigerate for up to 24 hours before baking. Freeze unbaked for up to 2 months. Try ground turkey for a leaner version.
