• Broccoli: I always use fresh broccoli florets in this recipe. However, you may want to use frozen broccoli if you’re pressed for time. If using frozen broccoli, there’s no need to pre-cook it but you must allow it to completely thaw and drain it well before adding it to the casserole.
• Long Grain Rice: You’ll need cooked long grain rice. If you have some leftover rice, that’s great. If not, consider purchasing the ready-to-serve rice specifically for this recipe (you’ll need two of the 8.8 ounce packs).
• Onion and Garlic: The combo adds great flavor to the cheese sauce.
• Milk: I prefer whole milk for this sauce. Use can substitute any type of milk you like and have on hand.
• Cream Cheese: Adds creaminess and a slight tang to the sauce.
• Colby Jack Cheese: Melts beautifully and adds a cheesy, gooey finish.

How I Make My Cheesy Broccoli Rice Casserole

1. Preheat the oven to 350°F. Lightly grease or spray an 11×7 casserole dish and set it aside.

2. Bring a pot of salted water to boil and add the broccoli. Cook for about 2 minutes. Drain and set aside.
3. Melt the butter in a large skillet over medium-high heat. Add the diced onions and cook until soft (about 3 minutes).
4. Add the garlic and cook for an additional 2 minutes.
5. Whisk in the flour and cook another 2 minutes.
6. Stir in the seasonings.

7. Using a whisk, slowly incorporate the milk. Whisk continuously to prevent lumps from forming.
8. Once all the milk has been added, add the cream cheese and 1 1/2 cups of the shredded Colby Jack cheese. Stir until bubbly, then turn off the heat.
9. Add the broccoli and cooked rice to the cheese sauce. Stir gently until everything is evenly incorporated.
10. Add the broccoli rice mixture to the prepared casserole baking dish and top with the remaining 1/2 cup of cheese.
11. Place in the preheated oven and bake for 35-40 minutes or until bubbly all around the outside.
12. Remove the dish from the oven and allow it to sit for 5 minutes before serving.

Recipe Troubleshooting Tips

• Lumpy Sauce: Be sure to whisk the milk slowly and continuously when adding it to the flour mixture to prevent lumps.
• Overcooked Broccoli: Cook the broccoli just until tender-crisp before adding it to the casserole. Overcooked broccoli can become mushy.
• Dry Casserole: If your casserole seems too dry, add a bit more milk to the cheese sauce next time.

Recipe Variations

• Add Protein: Make it a one-dish meal by adding your choice of cooked chicken or turkey (really great for using up leftover rotisserie chicken!).
• Different Cheeses: Swap Colby Jack with cheddar cheese, mozzarella, or a blend of your favorite cheeses.
• Spicy Kick: Add a pinch of cayenne pepper or red pepper flakes for some heat.

Serving Suggestions

This casserole is a great side dish option for almost any protein. We especially enjoy it with braised pork chops, roasted chicken, or grilled fish. Or serve it as a meatless meal option with a simple green salad and garlic bread on the side.

How I Store the Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions for 30 seconds to 1 minute or reheat the entire casserole in a 350 oven until warmed through.

👉 PRO TIP: Try stirring in a splash of milk before reheating to keep the casserole creamy.
