As someone who has lived her whole life in the South, I can tell you that casseroles are a staple here. They are a great way to put a lot of things together and serve a bunch of people. If you go to any Southern get-together, you’ll likely find at least 2-3 casseroles.

They are great because there are ways to make them for breakfast, dinner, appetizers, side dishes, even desserts.

Broccoli and cheese casserole is perfect as either a side dish or a main meal. Since the boys still don’t eat a lot, we were able to get away with this as our dinner one night. But it would also make a great side dish. I would pair it with some cooked ham or similar dish.

Broccoli and Cheese Casserole Step by Step

Ingredients

  • 2 heads broccoli, chopped
  • 3 tbsp butter, unsalted
  • 1 yellow onion, chopped
  • 2 cloves garlic, minced
  • 1/4 cup flour
  • 2 cups milk
  • 1/2 cup mayonnaise
  • 1 tbsp Dijon mustard
  • 1 tsp salt
  • 1 tsp pepper
  • 8 oz cheddar cheese, shredded
  • 40 club crackers, crushed
  • 2 tbsp parsley

Preparation

Preheat the oven to 350F. Steam the broccoli. I have a steamer basket that goes in a large stockpot and a steamer basket for my rice cooker. Either one will work. You could also purchase steamer broccoli from the frozen aisle in the grocery store.

Remove from the oven and spread the crushed crackers over the casserole. Set the oven to broil on low and broil for 2-3 minutes, until the crackers are brown. Let cool for about 10 minutes. Garnish with parsley and serve warm.

Leftovers

Store leftover broccoli and cheese casserole in an airtight dish in the refrigerator for up to 3 days. To reheat, place the entire casserole dish in a cool oven and bring it up to heat at 350F with the pan in there. This prevents the pan from shattering. Cook about 5 minutes, until it’s warmed through.

Broccoli and Cheese Casserole FAQs

Can Broccoli Casserole be made ahead of time?

Yes! Prepare the casserole and place it all in your baking dish. Cover and refrigerate (before cooking) for up to 24 hours. When you are ready to cook, make sure to let the baking dish come to room temperature (about 2 hours) before cooking. If you place a cold dish in a hot oven it can shatter.

Can it be frozen after cooking?

The broccoli and cheese casserole can be frozen if covered properly for up to one month. The day before you want to cook, let it thaw in the refrigerator. Then bring it to room temperature for about 2 hours before cooking.

Is it possible to add meat to the casserole?

You can add meat to the casserole. I have not personally tried it, but I would try cubed ham, shredded chicken, or browned ground beef.

  1. Broccoli and cheese go so well together. And this looks like it will pair nicely with a whole lot of main dishes. Love that it freezes well too!

  2. So I love cheese and I love broccoli but I could never do anything with them combined! Yours looks so good though!
