What Youโll Need

- Bacon: Chopped into small pieces.

How to Make Green Bean Casserole With Cheese
There are two parts to this dish, the cheese sauce and then assembling and baking the casserole. For full detailed directions see the recipe card at the bottom of this post.
- Blanch: Cook the green beans in boiling water just until beans turn bright green. Immediately rinse beans with cold water to stop the cooking process.
- Sautรฉ: Fry the chopped bacon in a skillet until crisp and remove. Cook the onion and garlic in the same skillet with the bacon grease.
- Cheese Sauce: Add the flour to the skillet to make a roux. Then slowly whisk in the liquid ingredients and add some of the shredded cheese.
- Assemble: Combine the green beans, cheese sauce, cooked bacon, and some of the cheese and fried onions. Transfer to a casserole baking dish. Top with remaining cheese and fried onions.
- Bake: Bake the casserole until bubbly and golden brown. Enjoy!
Cookโs Notes
This easy casserole just got even better! Read on for a few tips, tricks, and variations:
- Mix-Ins: Add in sautรฉed mushrooms, chopped pimientos, or slivered almonds on top to add more variety and crunch.
- Fresh, Frozen, or Canned: Fresh green beans work beautifully, but frozen green beans make a good substitute. Canned green beans create a softer, somewhat mushy finished dish.
- Feeling Cheesy? Try a different melting cheese such as colby-jack, mozzarella, gruyere or fontina. If using a milder variety, add a 1/2 teaspoon of prepared or ground mustard to the sauce. For a smoky flavor, try using a smoked cheese!

Make Ahead, Storing and Reheating
Just like the original, this cheesy green bean casserole recipe stores great for leftovers!
- Prepare Ahead: Prepare up to 2 days in advance, but do not add the crispy onions until ready to bake. Tightly cover the casserole and refrigerate for up to 2 days, or freeze the whole casserole for up to 3 months. Transfer frozen casserole to fridge and thaw completely, then top with fried onions and bake as directed.
- Leftovers: Store leftovers in fridge for up to five days. Sealed it tightly in an airtight container or tightly cover the original casserole dish in plastic wrap.
- Reheat: Bake the casserole again at 350ยฐF until heated through for about 20 minutes. This will help crisp up the French fried onions. You could also use the microwave individual portions, and sprinkle on extra fried onion topping for texture.
