INGREDIENTS
- 1 pound smoked bacon, cut into 1/2"-3/4" pieces: Adds a savory and crispy element to the casserole.
- 8 ounces sliced baby bella (crimini) mushrooms: Provides an earthy flavor and meaty texture.
- 1/2 medium yellow onion, sliced: Adds a sweet and aromatic base.
- 3 cloves garlic, minced: Infuses the dish with a robust, savory note.
- 1/4 cup all-purpose flour: Thickens the creamy sauce.
- 1 teaspoon kosher salt, more to taste: Enhances the overall flavor.
- 1/2 teaspoon fresh ground black pepper: Adds a hint of spice.
- 1-2 pinches red pepper flakes, to taste: Provides a subtle kick.
- 2 cups whole milk: Creates a rich and creamy sauce.
- 1 cup shredded sharp cheddar cheese: Melts into the sauce, adding a sharp, cheesy flavor.
- 24 ounces frozen green beans, thawed: The main vegetable component, providing a tender and fresh texture.
INSTRUCTIONS
- Step 1:
- In a cold large (12") cast iron skillet, add bacon. Turn heat to medium and cook until crisp, stirring occasionally. This will take about 25 minutes.
- Step 2:
- Remove bacon from the skillet with a slotted spoon and place on a paper towel-lined plate. Set aside. Pour bacon drippings into a jar to save for later use and return 4 tablespoons bacon drippings to the pan.
- Step 3:
- Return skillet to medium heat. Add mushrooms, onion, and garlic. Cook the vegetables until they are browned, about 5 minutes, stirring occasionally.
- Step 4:
- Add 2 tablespoons bacon drippings into the pan (or butter if you are out of bacon drippings). Add flour, salt, pepper, and red pepper flakes. Stir until the flour dissolves into the vegetables. Cook 1 minute to cook out the floury taste.
- Step 5:
- Add milk and stir to combine. Remove from the heat to prevent the cheese from getting grainy. Add the cheese a handful at a time and stir between each addition.
- Step 6:
- Once the cheese is completely melted into the sauce, add green beans and half of the cooked bacon.
- Step 7:
- Stir to combine, and return the skillet to medium heat. Continue to cook the casserole until the green beans are heated through and the sauce is thickened, about 3-5 minutes. Top with remaining bacon.
Serving and Storage Tips
Cheesy Green Bean Casserole is best served hot, straight from the skillet. This dish makes an excellent side for holiday dinners, family gatherings, or any comfort food meal. Pair it with roasted meats or serve it as part of a larger spread of vegetables and casseroles.
For storing leftovers, allow the casserole to cool completely before transferring it to an airtight container. Refrigerate for up to 3 days. To reheat, place the casserole in an oven-safe dish and warm it in the oven at 350°F (175°C) until heated through. Avoid microwaving as it can cause the sauce to separate and the green beans to become mushy.
Helpful Notes
For a quicker version of this recipe, you can use pre-cooked bacon or bacon bits instead of cooking the bacon from scratch. If you prefer a thicker sauce, you can add an extra tablespoon of flour when making the roux. To make this dish gluten-free, substitute the all-purpose flour with a gluten-free flour blend. According to culinary experts, adding a bit of grated Parmesan cheese on top before serving can enhance the flavor profile even more. Fresh herbs such as thyme or parsley can also be added for extra flavor and a touch of color.
