• 2 garlic cloves, minced – Because garlic makes everything better.
• 1 cup uncooked long-grain rice – Soaks up all that deliciousness.
• 2 cups beef broth – Rich, savory flavor that ties it all together.
• 1 (10.5 oz) can cream of mushroom soup – The creamy binder.
• 1 cup frozen peas and carrots (or mixed veggies) – Veggies without the chopping.
• 1 cup shredded cheddar cheese – Melts into golden cheesy goodness.

• Salt and pepper to taste

How to Make Cheesy Ground Beef and Rice Casserole (Step-by-Step)

Step 1: Preheat and Prep

First things first, preheat your oven to 350°F. Grease a 9×13-inch baking dish because we like our casseroles baked, not stuck.

Step 2: Sizzle the Beef and Onion

In a large skillet, brown the ground beef with chopped onion over medium heat. Give it 5-7 minutes, until everything is looking golden and delicious. Drain the grease—trust me, your future self will thank you.

Now stir in that minced garlic and cook for another minute. The smell? Chef’s kiss.

Step 3: Add the Rice, Broth, and Soup

Add uncooked long-grain rice directly into the skillet. Then pour in beef broth and cream of mushroom soup. Stir everything together like you’re mixing magic (because you kind of are).

Step 4: Toss in Veggies and Spices

Now’s the time for the peas and carrots (or mixed veggies—your kitchen, your rules). Add thyme, paprika, salt, and pepper. Give it a good stir until everything is coated and cozy.

Step 5: Transfer and Cheese It Up

Pour the mixture into your prepared baking dish. Smooth it out, then sprinkle that shredded cheddar cheese evenly across the top.

Step 6: Bake and (Optional) Top with Mozzarella

Cover with foil and bake for 25–30 minutes, until the rice is tender and the casserole is bubbling like a happy little volcano.

If you’re feeling extra cheesy (and really, who isn’t?), uncover, add mozzarella, and bake for another 5 minutes. Golden, bubbly perfection.

Step 7: Let It Rest (You Deserve It Too)

Once out of the oven, give your casserole a few minutes to rest. It’ll firm up, making it easier to serve and even tastier to eat.

Maria’s Real-Life Tip 💡

Can I be honest? This casserole became a hero in my kitchen one rainy Tuesday night when I was this close to ordering takeout again. My youngest was teething, my inbox was overflowing, and I had exactly 45 minutes before meltdown o’clock. I threw this together with what I had in the fridge, and my husband—bless him—said it was “better than restaurant food.” And boom, it made it into our regular dinner rotation.
