Ingredients You’ll Need

Here’s what goes into this creamy, dreamy casserole (and yes, it’s as delicious as it sounds):

• 6 strips bacon – Thick-cut or thin, your call! Just skip the bacon bits — we need that flavorful bacon fat for cooking.
• 1 yellow onion – Or white, sweet, even red; any kind will add that lovely caramelized base.
• 8 oz mushrooms – White button mushrooms work great, but baby bellas make a wonderful swap.
• 2 garlic cloves, minced – Fresh is best for full flavor, but jarred works in a pinch.
• 1 can (10.5 oz) cream of mushroom soup – Campbell’s classic never disappoints, though homemade is an option if you’re feeling fancy.
• ½ cup milk – Whole milk adds richness; heavy cream makes it extra indulgent.
• 1 cup Monterey Jack cheese, shredded – Melts beautifully and adds a subtle creamy tang.
• 4 cans (14.5 oz each) cut green beans, drained – Canned green beans give the perfect tenderness with minimal prep.
• 1 ½ cups French fried onions – The crown jewel of this casserole. Don’t skimp!

How to Make Green Bean Casserole

Alright, apron on and oven preheating — let’s get cooking! This Green Bean Casserole comes together in just a few easy steps. You’ll love how the kitchen fills with that cozy, savory aroma before it even hits the table.

1. Preheat the Oven

Start by preheating your oven to 350°F and lightly greasing a 9×13-inch baking dish with nonstick cooking spray. This ensures your casserole won’t stick and will slide out effortlessly once it’s bubbling and golden.

2. Cook the Bacon

In a large skillet, cook 6 strips of bacon over medium-low heat until they’re beautifully crispy. The key here is patience — slow cooking the bacon helps render more fat and keeps it from burning. Once cooked, transfer the strips to a paper towel-lined plate to drain, then crumble them into bite-sized bits.
Don’t toss that liquid gold! You’ll want to keep about 2 tablespoons of the bacon grease in the pan. It’s going to be the flavorful base for sautéing the veggies.

3. Sauté the Onions and Mushrooms

Add your diced onion to the skillet with the bacon grease and cook for about 5 minutes, or until it turns soft and translucent. Then toss in your mushrooms and cook another 5 minutes, stirring occasionally, until they’re tender and golden brown.
This step is where your kitchen really starts smelling amazing — that mix of caramelized onion and bacon is pure magic!

4. Add the Garlic for Depth

Once your veggies are golden, stir in freshly minced garlic and cook for just 30 to 60 seconds, or until fragrant. (If you can smell it, it’s done!) Garlic burns quickly, so keep an eye on it — we’re going for mellow and aromatic, not crispy.

5. Create the Creamy Sauce

Now, pour in your can of undiluted cream of mushroom soup, and add the crumbled bacon back into the skillet. Give it a good stir to combine everything. Then add milk and shredded Monterey Jack cheese, stirring until the cheese melts into the sauce.
The result? A thick, creamy, flavor-packed sauce that will coat every green bean in luscious goodness. Season it with a pinch of salt and freshly cracked pepper to taste.

💡 Pro Tip: If your sauce looks too thick at this point, you can stir in a splash more milk. If it looks too thin, let it simmer for a few extra minutes until it thickens slightly.

6. Add the Green Beans

Fold in the drained green beans gently, making sure every piece is coated in that savory, cheesy mixture. Don’t worry if the mixture looks a little soupy — it’ll thicken perfectly as it bakes.

7. Transfer to the Baking Dish

Pour everything into your prepared baking dish and spread it out evenly. This helps ensure the casserole cooks uniformly and every bite is full of creamy, bacon-infused flavor.

8. Add the Crunch

Sprinkle your French fried onions evenly across the top. They’re the star of the show when it comes to texture — that irresistible crispy topping gives each forkful the perfect crunch.

9. Bake to Golden Perfection

Bake the casserole uncovered for 30 minutes, or until it’s hot, bubbly, and the onions are lightly browned. If you want a little extra crunch, broil the top for the last 2–3 minutes — just keep a close eye on it to avoid burning.

10. Cool and Serve

Once it’s out of the oven, let it sit for about 5 minutes before serving. This quick rest allows the sauce to settle and makes it easier to serve perfect, creamy portions.

Cooking Tips for the Perfect Green Bean Casserole

• Don’t rush the onions and mushrooms. Let them cook slowly to bring out that natural sweetness — that’s your flavor base!
• Need to make it ahead? Assemble everything except the fried onions, cover, and refrigerate overnight. Add onions and bake when ready to serve.
• No Monterey Jack? Mozzarella or gouda make great backups.
• Want a little heat? Add a dash of cayenne or crushed red pepper flakes to the creamy sauce.

And if your sauce looks a bit too thick — relax. That’s just extra comfort waiting to happen.
