For the Savory Base:
1 lb Ground Beef (80/20 for best flavor)
1 medium Yellow Onion, diced
3 cloves Garlic, minced
1 (24 oz) jar Marinara Sauce or 3 cups homemade
1 (14.5 oz) can Diced Tomatoes, undrained
1 tablespoon Italian Seasoning
1 teaspoon Dried Oregano
Salt & Black Pepper, to taste
For the Hearty Body:
12 oz Pasta (elbow, rotini, penne, or shells), cooked al dente
2 cups Frozen Mixed Vegetables (peas, carrots, corn, green beans)
1 ½ cups Shredded Mozzarella Cheese
1 cup Shredded Cheddar Cheese
For the Optional Crispy Topping:
½ cup Panko Breadcrumbs
2 tablespoons Grated Parmesan Cheese
2 tablespoons Melted Butter
1 tablespoon Fresh Parsley, chopped
The Method: Effortless, Flavor-Packed Layers
Phase 1: Build the Flavor Foundation
Brown the Beef: Preheat oven to 375°F (190°C). In a large oven-safe skillet or Dutch oven, cook ground beef and onion over medium-high heat until beef is browned. Drain excess fat.
Season & Simmer: Add garlic, Italian seasoning, oregano, salt, and pepper; cook for 1 minute until fragrant. Stir in marinara sauce and diced tomatoes. Bring to a simmer and cook for 5 minutes.
Phase 2: Assemble the Casserole
Combine: To the skillet (or transfer to a greased 9x13-inch baking dish), add the cooked pasta and frozen vegetables. Stir until everything is evenly coated in sauce.
Cheese Layer: Sprinkle the shredded mozzarella and cheddar cheeses evenly over the top.
Phase 3: The Golden-Brown Bake
Add Topping (Optional): In a small bowl, mix panko, parmesan, melted butter, and parsley. Sprinkle evenly over the cheese.
Bake: Bake, uncovered, for 20-25 minutes, until the cheese is fully melted, the casserole is bubbling around the edges, and the topping is golden.
Phase 4: The Perfect Rest
Cool & Serve: Let the casserole rest for 5-10 minutes before serving. This allows it to set slightly for perfect scooping.
Pro-Tips for Casserole Mastery
Undercook the Pasta: Cook pasta 2 minutes less than package directions. It will finish cooking in the oven, absorbing sauce without becoming mushy.
Drain the Beef Well: Removing excess fat prevents a greasy final dish.
Make-Ahead Magic: Assemble the casserole (without baking) up to 24 hours ahead. Cover and refrigerate. Bake as directed, adding 5-10 minutes to the bake time.
Freezer Friendly: Cool completely, cover tightly, and freeze for up to 3 months. Thaw overnight in fridge before reheating, covered, at 350°F until hot throughout.
Serving Your Hearty Masterpiece
