how to make broccoli casserole

Step 1: Prepare the chopped mushrooms, fresh minced garlic, and diced yellow onion.

Step 2: Cook the veggies until soft and the mushrooms have released and cooked off their liquid.

Step 3: Add the cooked mushroom, garlic, and onion to a bowl along with the sour cream, cream of mushroom soup, frozen broccoli florets and one cup of the sharp cheddar cheese. 

Tip: Make sure you buy a bag of broccoli florets and not broccoli cuts, or you will end up with a lot of stems instead of broccoli heads.

Give it all a stir until it is totally combined and the broccoli is coated.

Be sure not to skip grating the cheddar cheese yourself, as it is so much fresher and the flavor is so delicious!

I used sharp cheddar cheese in this recipe, but a mild or medium cheddar would also be delicious.

Step 4: Grease a small casserole dish, then pour the broccoli casserole filling in.

Step 5: Top with the remaining one cup of sharp cheddar cheese.

Step 6: Crush up one sleeve of ritz crackers and crumble it over the top of the casserole. 

The easiest way to do this is add the crackers to a gallon sized ziploc bag, press out the air, and crush the crackers with your hands.

Step 7: Bake the broccoli casserole at 350 degrees for around 30 minutes, or until the ritz crackers are browned and the filling is nice and bubbly.
