Pepper and Salt: Simple seasonings that enhance all the other flavors.
Garlic: Adds that wonderful aromatic depth that ties everything together.
Parmesan Cheese: The final touch that brings a nutty, salty finish. Always use freshly grated if you can!

How to Make Green Bean Casserole with Bacon

Step 1: Prepare Your Ingredients

Preheat your oven to 350°F and spray a 9×13 casserole dish with non-stick cooking spray. Having everything ready makes assembly quick and easy.

Step 2: Mix the Base

In a large bowl, combine your steamed green beans, cream of celery soup, half and half, 1 cup of Colby jack cheese, pepper, salt, and minced garlic. Stir until everything is well-coated in the creamy mixture.

Step 3: Transfer to Baking Dish

Pour the green bean mixture into your prepared casserole dish, spreading it out evenly to ensure consistent cooking.

Step 4: Add the Toppings

Sprinkle the remaining Colby jack cheese over the top, followed by the French fried onions and crumbled bacon. This layering ensures you’ll get that perfect crispy, cheesy topping.

Step 5: Bake to Perfection

Bake the casserole uncovered for 25 minutes, until it’s heated throughout and the cheese is gloriously bubbly.

Step 6: Finish and Serve

Top with a sprinkle of parmesan cheese just before serving for that final flavor boost. Serve while warm and watch it disappear!

Pro Tips for Making the Recipe

Steam Beans Properly: Make sure your green beans are just tender-crisp before adding to the mixture. Overcooked beans will become mushy in the casserole.
Bacon Secret: Cook your bacon until extra crispy, as it will soften slightly during baking with the moist ingredients.
Cheese Strategy: Save some cheese for the very top layer to create that perfect golden crust.
Rest Before Serving: Let the casserole sit for 5 minutes after baking to set up properly and make serving easier.

How to Serve

This versatile casserole pairs beautifully with so many main dishes:

Holiday Meals:

Serve alongside roasted turkey, honey-glazed ham, or prime rib for a memorable holiday spread.

Weeknight Dinners:

Pair with a simple roasted chicken, grilled steak, or even a hearty meatloaf for an elevated everyday meal.

Potluck Perfect:

This casserole travels well and stays delicious at room temperature, making it ideal for potlucks and family gatherings.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 4 days. The flavors actually continue to develop, making day-two servings sometimes even better!

Freezing

For longer storage, freeze the casserole without the cheese, onion, and bacon toppings in a freezer-safe container for up to 6 months. Add these toppings fresh when you’re ready to reheat.

Note: If planning to freeze, slightly undercook the green beans initially, as they’ll soften more during the reheating process.

Reheating

For best results, reheat the casserole in a 375°F oven for about 20 minutes until warm and bubbly. If frozen, thaw overnight in the refrigerator first. Add fresh toppings before reheating for the best texture.

For quick individual servings, microwave portions for 2-4 minutes on high power, though the texture of the onions won’t be as crispy.

FAQs

Can I use fresh green beans instead of frozen?
Absolutely! Fresh green beans work wonderfully. Simply trim the ends and cut them into 2-inch pieces before steaming. They actually provide a better texture than frozen beans, with a perfect tender-crisp bite.

Can I make this vegetarian by skipping the bacon?
You certainly can. For a meatless version, simply omit the bacon and consider adding extra French fried onions or even some toasted sliced almonds for that crunchy texture. You might want to add a bit more seasoning to compensate for the flavor the bacon provides.

What can I substitute for cream of celery soup?
If you don’t have cream of celery soup, cream of mushroom makes an excellent substitute. For a homemade alternative, make a simple roux with 2 tablespoons each of butter and flour, then whisk in 1 cup of chicken broth and ½ cup of milk, seasoning with celery salt and pepper.

Can I prepare this the night before and bake it the next day?
This works beautifully as a make-ahead dish! Prepare everything through Step 3, cover and refrigerate overnight. The next day, bring it to room temperature for about 30 minutes, add the toppings, and bake as directed. You might need to add 5-10 minutes to the baking time if it’s still cool from the refrigerator.
