Ultimate Green Bean Casserole Ingredients
Ready to whip up this classic comfort dish? Here’s everything you need!
For the Casserole
- Bacon – Adds a delightful smokiness; for a non-pork version, turkey bacon works wonderfully.
- Yellow Onion – Brings sweetness and depth; feel free to use sweeter varieties like Vidalia for a milder flavor.
- Chopped Button Mushrooms – Infuses umami richness; substitute with cream of celery if you’re avoiding mushrooms.
- Garlic (minced) – Enhances overall flavor; pre-minced garlic can save you time in the kitchen.
- Cream of Mushroom Soup – The sauce’s base must be undiluted for the right consistency; try cream of chicken as an alternative.
- Milk – Adds creaminess; for a richer taste, consider half-and-half or whole milk.
- Shredded Monterey Jack Cheese – Melts beautifully and adds a mild flavor; mozzarella is a great substitute if preferred.
- Canned Cut Green Beans – The main vegetable delivers tenderness; opt for fresh or frozen beans if you blanch them first.
For the Topping
- French Fried Onions – Provides a crunchy top layer; crushed crackers can also add that desired crunch if you’re in a pinch.
Now that you have your ingredients for the Ultimate Green Bean Casserole, let’s get cooking! Don’t forget the joy that comes with making this beloved dish, perfect for any gathering or cozy night in.
Step‑by‑Step Instructions for Ultimate Green Bean Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take a 9×13-inch baking dish and lightly grease it with cooking spray or a touch of butter. This will ensure your Ultimate Green Bean Casserole doesn’t stick to the sides during baking, allowing for easy serving later.
Step 2: Cook the Bacon
In a large skillet, cook about 6 slices of bacon over medium heat until they are nice and crispy, roughly 8–10 minutes. Once cooked, carefully transfer the bacon to a plate lined with paper towels to drain the excess grease. Reserve about 1 tablespoon of the bacon drippings in the skillet, as this will enhance the flavor of your filling.
Step 3: Sauté the Vegetables
In the same skillet with the reserved bacon drippings, add one diced yellow onion, cooking until they become translucent for about 3–4 minutes. Next, incorporate 8 ounces of chopped button mushrooms and 2 minced garlic cloves, stirring continuously until fragrant, which should take another 2–3 minutes. The vegetables should be tender and slightly golden.
Step 4: Make the Sauce
Now, stir in a can of undiluted cream of mushroom soup, the crumbled bacon, and ½ cup of milk into the skillet. Mix everything until well combined and smooth. Let the mixture bubble gently for about 2 minutes on low heat, allowing the flavors of the Ultimate Green Bean Casserole to meld beautifully together.
Step 5: Combine the Green Beans
Carefully fold in 2 cans of drained cut green beans into the skillet. Add salt and freshly ground pepper to taste, ensuring all ingredients are evenly coated in the creamy sauce. The green beans should be thoroughly mixed into the filling, ready for the final step of assembly.
Step 6: Assemble the Casserole
Pour the green bean and sauce mixture into your prepared baking dish, spreading it out evenly. To add a delightful crunch, top it off with about 1 ½ cups of French fried onions, spreading them generously over the surface. This creates a wonderful texture that contrasts beautifully with the creamy filling.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for about 30 minutes, or until the casserole is bubble and the onions are golden brown. Keep an eye on it in the final moments to prevent any over-browning of the crunchy topping. The aroma will fill your kitchen, signaling that your Ultimate Green Bean Casserole is nearly ready.
Make Ahead Options
The Ultimate Green Bean Casserole is the perfect dish for busy home cooks looking to save time on family gatherings! You can assemble the casserole, minus the French fried onions, up to 24 hours in advance. Simply prepare the filling, transfer it to the baking dish, and cover tightly with plastic wrap before refrigerating. This helps maintain freshness and prevents the green beans from browning. When you’re ready to serve, just add the onions on top and bake at 350°F (175°C) for about 30 minutes until bubbly and golden. This way, you’ll enjoy your flavorful, homemade casserole without the last-minute rush—just as delicious as when freshly made!
