Step-by-step instructions
- Preheat and prepare: Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil.
- Sauté aromatics: Heat 2 tablespoons olive oil in a skillet over medium heat. Sauté the chopped onion until translucent, about 4–5 minutes. Add garlic for the last 30 seconds.
- Mix the meatloaf base: In a large bowl, combine ground beef, sautéed onion and garlic, milk, egg, breadcrumbs, salt, pepper, oregano, and 1/2 cup ketchup. Mix gently with your hands until just combined — overmixing makes meatloaf dense.
- Layer the casserole: Press half the meat mixture into the bottom of the prepared baking dish to form an even layer. Scatter the thawed mixed vegetables over the meat layer, then sprinkle with half of the cheddar and mozzarella cheeses. Spread the remaining meat mixture on top and smooth.
- Top and bake: Spread a thin layer of ketchup over the top of the meatloaf layer, then finish with the remaining shredded cheeses. Bake for 35–45 minutes, until the internal temperature reaches 160°F (71°C) and the top is golden and bubbly.
- Rest, slice, and serve: Let the casserole rest for 10 minutes before slicing. This helps the layers set and makes serving cleaner.
If you love cheesy, saucy toppings, this recipe plays nicely with ideas from lighter snacks too — try experimenting with textures inspired by our air-fryer cheesy chicken nachos.
Tips for success
- Don’t overmix: Combine ingredients until just blended to keep the meat tender.
- Use a thermometer: Aim for an internal temp of 160°F (71°C) for ground beef to ensure safe doneness without drying.
- Even layers: Press the bottom meat layer firmly and distribute vegetables evenly so every slice has balance.
- Cheese choice: A mix of cheddar and mozzarella gives great flavor and melt. For a sharper bite, swap half of the cheddar for smoked cheddar.
- Make-ahead: Assemble the casserole up to a day ahead, cover, and refrigerate. Bring to room temperature before baking. For more make-ahead casserole ideas, see this angel chicken and rice casserole for storage and timing tips.
Possible variations
- Gluten-free: Swap regular breadcrumbs for gluten-free breadcrumbs or crushed gluten-free crackers. Use gluten-free ketchup if needed.
- Streusel topping: For a crunchy twist, mix 1/2 cup panko (or gluten-free panko), 2 tablespoons melted butter, and 1 tablespoon grated Parmesan; sprinkle over the cheese for the last 10 minutes of baking to toast the topping.
- Lighter version: Substitute half the ground beef with ground turkey and reduce the cheese slightly.
- Change the protein: Swap for ground chicken or turkey; for a spicier fall variation try flavors reminiscent of our spicy southern cheesy chicken spaghetti casserole by adding a touch of cayenne and smoked paprika.
Storage recommendations
- Refrigerator: Cover leftover slices tightly and store in an airtight container for up to 3 days.
- Freezer: Wrap individual portions in plastic wrap and foil and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm in a 350°F (175°C) oven for 15–20 minutes covered with foil, or microwave on medium power in 1–2 minute intervals until heated through.
