What You’ll Need (Ingredients)

• 1 lb ground beef (85–90% lean works best)
• 4 cups broccoli florets (fresh or frozen; bite-size pieces)
• 1 small yellow onion, finely diced
• 3 cloves garlic, minced
• 1 cup cooked rice (white, brown, or cauliflower rice for low-carb)
• 1 cup beef or chicken broth
• 1 can (10.5 oz) cream of mushroom soup (or cream of chicken)
• 1/2 cup sour cream or Greek yogurt
• 2 cups shredded cheese (cheddar, Colby-Jack, or a mix)
• 2 tbsp soy sauce (or coconut aminos)
• 1 tsp Dijon mustard (optional but recommended)
• 1 tsp onion powder
• 1/2 tsp smoked paprika
• 1/2 tsp black pepper
• 1/2 tsp kosher salt (adjust to taste)
• 2 tbsp olive oil or butter
• Optional topping: 1/2 cup crushed Ritz crackers or panko + 1 tbsp melted butter

Step-by-Step Instructions

1. Preheat the oven. Set to 375°F (190°C).

   Grease a 9×13-inch baking dish.

2. Prep the broccoli. If fresh, steam or blanch for 2–3 minutes until bright green and slightly tender. If frozen, thaw and pat dry. We don’t want soggy casserole energy.
3. Brown the beef. Heat a large skillet over medium-high, add oil, then cook ground beef until no longer pink, 5–7 minutes.

   Break it up as it cooks.

4. Add aromatics. Stir in onion and cook 3–4 minutes until softened. Add garlic and cook 30 seconds until fragrant.
5. Season the base. Stir in soy sauce, onion powder, smoked paprika, black pepper, and salt. Taste.

   Adjust now so the whole dish sings later.

6. Make it creamy. Reduce heat to medium. Stir in cream of mushroom soup, sour cream, Dijon, and broth. Simmer 2–3 minutes until smooth and slightly thick.
7. Combine the stars. Fold in cooked rice, broccoli, and 1 cup shredded cheese.

   Mix gently to coat everything in the sauce.

8. Assemble. Transfer mixture to the baking dish. Sprinkle the remaining 1 cup cheese on top. If using a crunchy topping, mix crackers/panko with melted butter and scatter over the cheese.
9. Bake. Bake 18–22 minutes until bubbly at the edges and golden on top.

   If you love deeply browned cheese, broil for 1–2 minutes at the end. Watch closely—burnt cheese is a tragedy.

10. Rest and serve. Let it sit 5–10 minutes so it sets up. Garnish with chopped parsley or green onions if you’re feeling fancy.

    Serve warm.

Storage Tips

• Fridge: Store leftovers in an airtight container for up to 4 days. Reheat covered at 350°F for 15–20 minutes or microwave in 60–90 second bursts.
• Freezer: Freeze tightly wrapped portions for up to 3 months. Thaw overnight in the fridge and reheat covered until hot.
• Make-ahead: Assemble up to 24 hours in advance, cover, and refrigerate.

  Add 5–10 minutes to the bake time if starting cold.

Why This is Good for You

• Protein power: Ground beef delivers iron, B12, and protein for steady energy and satiety.
• Broccoli benefits: Fiber, vitamin C, and sulforaphane compounds that support cellular health. Basically, broccoli’s the quiet overachiever.
• Smart carbs: Using rice (or cauliflower rice) lets you control the carbs and meet your goals, whether that’s muscle gain or a lighter plate.
• Balanced macros: Protein + fiber + fats = fewer cravings later. FYI, that’s how you avoid the 9 p.m. snack raid.

Avoid These Mistakes

• Skipping the pre-cook on broccoli: Raw florets can stay too firm and water down the sauce.

  Quick blanch or steam is key.

• Under-seasoning the beef: This is the flavor engine. Taste as you go and adjust salt, soy, and spices.
• Too much liquid: If your broccoli is wet or you add extra broth “just because,” you’ll get soupy casserole. Pat dry and measure.
• Overbaking: Dry casserole is sad.

  Bake until bubbly and set, then rest. Don’t incinerate it.

• Cheese overload up top: Wild take, but a 3-inch cheese blanket can prevent browning and trap steam. Two cups total is the sweet spot.

Different Ways to Make This

• Low-carb: Swap rice for 2 cups cauliflower rice.

  Reduce broth to 1/2 cup to avoid excess moisture.

• Spicy: Add 1 tsp crushed red pepper or a diced jalapeño with the onions. A drizzle of sriracha on top? Chef’s kiss.
• Mushroom lover’s: Sauté 8 oz sliced mushrooms with the onions for umami overload.
• Tex-Mex twist: Use pepper jack cheese, add 1 tsp chili powder + 1/2 tsp cumin, and fold in a can of diced green chiles.
• Health boost: Stir in 1 cup spinach or kale at the end of the skillet step; it wilts instantly and disappears into the mix.
• Dairy-free: Use dairy-free cream soup, plant-based yogurt, and vegan mozzarella.

  Use oil instead of butter for the topping.

• Gluten-free: Choose gluten-free cream soup and tamari; use GF panko or skip the crumb topping.

FAQ

Can I use ground turkey instead of beef?

Yes. Use 93% lean ground turkey and add 1 tablespoon olive oil for richness. Taste and bump the soy sauce, paprika, and pepper for extra flavor since turkey is milder.

Do I have to cook the rice first?

For best texture, yes.

Pre-cooked rice prevents a mushy or underdone casserole. If using instant rice, reduce the broth slightly and expect a softer finish.

What cheese works best?

Sharp cheddar brings classic flavor and melts well. Colby-Jack is creamier, and Monterey Jack melts like a dream.

Avoid pre-shredded if possible; freshly grated melts better, IMO.

How do I make it without canned soup?

Whisk 2 tbsp butter, 2 tbsp flour, and 1 cup milk or broth in a saucepan until thick. Season with salt, pepper, and a pinch of garlic/onion powder. Use as a 1:1 replacement.

Can I assemble and freeze before baking?

Yes.

Assemble without the crunchy topping, wrap tightly, and freeze up to 3 months. Thaw overnight, add topping, then bake covered for 20 minutes and uncovered for 15–20 more.

Why is my casserole watery?

Likely from wet broccoli or extra broth. Pat broccoli dry, measure liquids, and let the baked casserole rest 5–10 minutes so it firms up.

What sides pair well?

A crisp green salad with a tangy vinaigrette, roasted carrots, or garlic bread.

Keep it simple—the casserole does the heavy lifting.
