1 ½ cups cooked rice – You can use white rice or brown rice for a heartier dish. Brown rice adds a bit more texture and nutrients, but either works great.
4 cups broccoli florets – Whether you use fresh or frozen broccoli, both give a fantastic result. If you’re using fresh, make sure to blanch the broccoli for a couple of minutes to soften it before adding to the casserole.
1 can (10.5 oz) cream of mushroom soup – This classic ingredient creates a rich, creamy base. If you prefer a different flavor, you can substitute with cream of chicken soup or a vegetarian option.
1 ½ cups shredded cheddar cheese – This is the secret to that cheesy, melty goodness we all love in casseroles. Feel free to add more if you’re a cheese lover!
½ cup milk – This helps achieve that perfect creamy texture, blending the cheese and soup.
1 small onion – Chopped finely, the onion adds a hint of sweetness and depth to the flavor profile.
2 cloves garlic – Minced, to enhance the savory aroma and flavor.
Salt and pepper – To taste, ensuring all the flavors come together perfectly.
¼ cup breadcrumbs – Optional, but adding breadcrumbs on top creates a crispy, golden layer that’s simply irresistible.
