Simple Ingredients & Substitutions
- Frozen chopped broccoli. Not all frozen broccoli is the same! I’ve tried different versions and the BEST product for this recipe is the chopped broccoli that’s sold in those little square boxes. It’s chopped small so it’s the perfect size for mixing and eating. Let it thaw in the fridge overnight, or heat it according to package directions.
- Eggs. Use large eggs lightly beaten so they integrate easily into the mixture.
- Cream of Mushroom soup. I don’t recommend using low sodium for this but if you do, add about a half teaspoon of salt to the recipe. You can sub with cream of chicken condensed soup, too.
- Dried onion flakes. This pantry staple adds flavor without having to chop onions. Substitute with about ¾ teaspoon onion powder.
- Mayonnaise. Use regular mayo for rich creamy flavor. If you really want to use light mayo that’s fine too.
- Sharp cheddar cheese. Get a block and shred it yourself. It has more flavor, melts better, and you actually get more volume! An 8-ounce block gives you more cheese than an 8-ounce package of pre-shredded.
- French’s fried onions. Use a large can so you have enough to mix into the casserole and to top it at the end.
Additions & Variations
This recipe can be adapted to your taste in a variety of ways.
- If you want to make your casserole a main dish, add some protein like cooked chicken, turkey, or ham to the broccoli mixture.
- Try other cheeses for variety, including parmesan or gruyere.
- For a crispy topping alternative, sprinkle some crushed crackers (Ritz crackers), panko, or breadcrumbs over the casserole before baking.
How to Make It
- In a large bowl, combine broccoli with the rest of the ingredients, saving some crunchy onions for topping, until well combined.
- Stir in 1 cup of fried onions and spread the mixture evenly in a large baking dish.
- Bake uncovered for 35 to 40 minutes or until bubbly.
- Sprinkle the remaining onions on top and bake for another 5 minutes or until golden.
- Thaw the broccoli completely before putting it in the oven, and drain excess water. This will insure it cooks evenly.
- Use a 9 x 11-inch baking dish.
- Prepare the casserole ahead of time, cover with plastic wrap or aluminum foil and refrigerate for up to a day. Then bake it when your guests arrive.
- This casserole is perfect for cheese lovers. Make a second casserole dish for large crowds.
Store leftovers tightly covered with plastic wrap, foil or an airtight container, and refrigerate for up to 3 days. Once you’re ready to reheat the casserole, let it sit on the counter and come to room temperature then bake or dish it into a plate and reheat in the microwave.
To freeze the casserole, let it cool down completely, cover it with plastic wrap or foil and freeze for up to three months. Thaw in the refrigerator overnight, then bake or reheat.
This comforting side dish is the perfect addition to any menu or holiday buffet. Serve this creamy casserole with these main dishes and sides.
