Equipment

  • Large skillet
  • 9×13 baking dish
  • Mixing bowl

Ingredients
  

For the beef mixture

  • 1.5 pounds lean ground beef (85/15 or 90/10)
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon red pepper flakes (optional)
  • Salt and pepper to taste

For the broccoli

  • 4 cups fresh broccoli florets (about 2 medium heads), cut into bite-sized pieces
  • 1 tablespoon water

For the cheese sauce

  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 1.5 cups milk (2% or whole works best)
  • 1/4 teaspoon nutmeg (the secret ingredient!)
  • 1 cup shredded cheddar cheese
  • 1 cup shredded mozzarella cheese, divided
  • 1/2 cup grated Parmesan cheese, divided
  • Salt and pepper to taste

For assembly

  • 2 cups cooked rice (white or brown)
  • 1/2 cup breadcrumbs (panko preferred for crunch)
  • 1 tablespoon butter, melted
  • 1 tablespoon fresh parsley, chopped (for garnish)

Instructions
 

Step 1: Prep Work

  • Preheat your oven to 375°F (190°C) and lightly grease a 9×13 baking dish.
  • Cook the rice according to package directions if you haven't already. Set aside.

Step 2: Cook the Beef

  • Heat olive oil in a large skillet over medium-high heat until shimmering.
  • Add diced onion and cook for 2-3 minutes until beginning to soften.
  • Add ground beef and break it apart with a wooden spoon. Season with salt and pepper.
  • Cook until beef is no longer pink, about 5-7 minutes, stirring occasionally.
  • Add minced garlic, oregano, basil, and red pepper flakes (if using). Cook for another minute until fragrant.
  • Drain excess fat if necessary and set the beef mixture aside.

Step 3: Prepare the Broccoli

  • Place broccoli florets in a microwave-safe bowl with 1 tablespoon of water.
  • Cover with a plate or microwave-safe lid and microwave on high for 2-3 minutes until broccoli is bright green and just barely tender (it will cook more in the oven).
  • Drain any excess water and set aside.

Step 4: Make the Cheese Sauce

  • In the same skillet (wipe clean if necessary), melt 2 tablespoons butter over medium heat.
  • Add flour and whisk constantly for about 1 minute to create a roux. It should smell slightly nutty but not brown.
  • Gradually pour in milk while continuing to whisk to prevent lumps.
  • Bring mixture to a gentle simmer, whisking frequently, until it begins to thicken (about 3-4 minutes).
  • Add nutmeg and a pinch of salt and pepper.
  • Reduce heat to low and add the cheddar cheese, 1/2 cup of mozzarella, and 1/4 cup of Parmesan. Stir until smooth and fully melted.
  • Taste and adjust seasoning as needed.

Step 5: Assemble and Bake

  • Spread the cooked rice in an even layer in the prepared baking dish.
  • Top with the beef mixture, spreading it evenly over the rice.
  • Arrange the broccoli florets over the beef layer.
  • Pour the cheese sauce evenly over everything, making sure to cover all the broccoli (this prevents it from drying out in the oven).
  • Sprinkle with remaining 1/2 cup mozzarella and 1/4 cup Parmesan cheese.
  • In a small bowl, mix breadcrumbs with 1 tablespoon of melted butter, then sprinkle over the top of the casserole.
  • Bake uncovered for 25-30 minutes until the casserole is bubbling and the top is golden brown.
  • Allow to rest for 5 minutes before serving. Garnish with fresh parsley if desired.

Notes

  • Rice options: Brown rice adds more nutrition and a nutty flavor, while white rice is milder. For a lower-carb option, cauliflower rice works well too!
  • Make ahead magic: You can assemble the entire casserole up to 24 hours ahead and refrigerate, covered. Add 10-15 minutes to the baking time if cooking from cold.
  • Freezer friendly: This casserole freezes beautifully for up to 3 months. Thaw overnight in the refrigerator before baking.
  • Leftover love: Leftovers will keep in the refrigerator for 3-4 days and actually taste amazing reheated.
  • Veggie variations: Not a broccoli fan? Cauliflower, green beans, or a mix of bell peppers also work great in this recipe.

Common Mistakes to Avoid

  • Overcooking the broccoli. The microwave step is just to par-cook it – you want it bright green and still slightly crisp since it will continue cooking in the oven. Mushy broccoli = sad casserole.
  • Skipping the roux. That butter-flour mixture is crucial for a smooth, thick cheese sauce. Without it, your sauce might be thin and watery or the cheese could separate during baking.
  • Using pre-shredded cheese. Those convenient bags of shredded cheese contain anti-caking agents that can make your sauce grainy. For the smoothest, creamiest results, buy blocks and shred them yourself.

Variations & Customizations

  • Kid-Friendly Version: If you have picky eaters, chop the broccoli into smaller pieces or even pulse it in a food processor so it’s less noticeable. Add a cup of corn for natural sweetness kids love.
  • Spicy Kick: Double the red pepper flakes and add a diced jalapeño to the beef mixture. Use pepper jack cheese in place of mozzarella for an extra kick.
  • Fancy It Up: Substitute ground beef with browned Italian sausage or even diced grilled steak. Add 8 oz of sautéed mushrooms and a splash of white wine to the cheese sauce for more complex flavor.

FAQs

Can I use frozen broccoli instead of fresh?

Absolutely! Use the same amount (4 cups) but skip the microwave step. Thaw and drain it well before adding to the casserole to prevent excess water.

What if I don’t have all three cheeses?

You can simplify with just cheddar if needed, but the blend of cheeses adds great depth of flavor. If you only have two types, adjust the quantities to maintain the total amount of cheese.

Can I add pasta instead of rice?

Yes! Short pasta like penne or rotini works wonderfully in this recipe. Cook it 1-2 minutes shy of al dente since it will continue cooking in the oven.

Final Thoughts

There’s something wonderfully comforting about a well-made casserole. It’s unpretentious food that fills both belly and soul, perfect for gathering family around the table or dropping off at a neighbor’s house when they need some care. This beef, broccoli and cheese casserole might not win any haute cuisine awards, but it will win you plenty of clean plates and requests for seconds. And isn’t that the true measure of a successful recipe? The combination of savory beef, nutritious broccoli, and creamy cheese sauce creates a balanced meal that satisfies on every level – and might just save the day when your own dinner plans go awry!
