What You Need to Make It

Every ingredient here earns its place. The veggie layer builds a hearty base, and the beef layer brings all the richness that makes this a real meal.

• Broccoli, cauliflower, and carrots roasted until the edges brown for the best texture
• Olive oil, garlic powder, sea salt, black pepper, and parmesan cheese the simple toss that makes those veggies shine
• Ground beef, diced onion, and marinara sauce the hearty, savory layer that pulls everything together
• Italian seasoning and mozzarella cheese the finishing touch that makes this a proper baked casserole

Note: Shred your mozzarella from a block if you can it melts smoother and gets that deeper, golden bubbly top.

How to Make It

The method is simple: roast the veggies, build the beef layer, then layer and bake. Here’s how it comes together:

1. Preheat your oven to 400 degrees F and line a large baking sheet with foil.
2. Toss broccoli, cauliflower, and carrots with olive oil, garlic powder, salt, pepper, and parmesan. Spread in a single layer and roast 25-30 minutes, tossing halfway, until edges are browned.
3. While the veggies roast, heat olive oil in a skillet. Saute the diced onion 5-7 minutes, then add ground beef, season with salt and pepper, and cook until browned.
4. Stir in the marinara sauce and Italian seasoning. Simmer 2 minutes, then remove from heat.
5. Layer the roasted veggies into a 9×13 casserole dish. Spoon the beef mixture over the top and spread evenly. Sprinkle with mozzarella.
6. Bake 10-15 minutes until hot and bubbly. Broil 1-3 minutes for a golden top if you like.

Pro Tip: After testing this more times than I can count, the biggest advice is not to skip the broil those extra minutes take the mozzarella from melted to gloriously golden.

Can You Make This Ground Beef Casserole Ahead of Time?

Yes and it actually works beautifully for meal prep. You can roast the vegetables and cook the beef layer separately, then store them in the fridge until you’re ready to assemble and bake.

• Roasted veggies keep well in the fridge for up to 3 days before assembling
• The cooked beef marinara layer stores in an airtight container for 3 days
• Assemble the full dish, cover tightly, and refrigerate overnight then bake when ready

Storage and Reheating Tips

Leftovers from this cheesy ground beef casserole reheat well, which makes it a great cook-once, eat-twice kind of meal.

• Store in an airtight container in the refrigerator for up to 3-4 days
• Reheat in the oven at 350 degrees F for best texture, or microwave for a quick lunch
• Freeze individual portions in sealed containers for up to 2 months thaw overnight before reheating

Note: The veggies hold up better than you’d expect after reheating, especially when warmed in the oven rather than the microwave.

This Cheesy Ground Beef Casserole Is Your New Weeknight Hero

This Cheesy Ground Beef Casserole comes together in about 30 minutes, and honestly, the hardest part is waiting for that bubbly, golden mozzarella top to cool enough to dig in. The roasted veggies underneath get soft and a little caramelized at the edges, the beef layer is rich and saucy, and the whole thing fills the kitchen with the kind of smell that brings everyone to the table before you’ve even called them. You’ll love how it turns out every single time.

A couple of things worth remembering: don’t skip the broil at the end even just those few minutes take the mozzarella from melted to genuinely golden and gloriously bubbly, and it’s worth every second. If you’re prepping ahead, the beef and veggie layers store separately in the fridge for up to three days, so Tuesday night can practically take care of itself. And shredding your mozzarella from a block instead of reaching for the pre-shredded bag? That little swap makes a real difference in how it melts the kind of trick that sounds small until you see that cheese pull.
