Ingredients Breakdown
- Fresh Green Beans: Keep them vibrant and crisp by blanching them first. Frozen works too, but avoid canned for the best texture.
- Thick-Cut Bacon: Adds smoky depth and a little crunch. Turkey bacon can be swapped in for a lighter version.
- Onions and Garlic: Caramelized onions bring sweetness that balances the creaminess.
- Mushrooms: Fresh mushrooms deepen the umami flavor, but you can skip them if you’re not a fan.
- Heavy Cream and Chicken Broth: This duo makes the sauce silky and rich. Swap heavy cream for a mix of milk and cream if needed.
- Shredded Cheddar Cheese: Go for sharp cheddar to add a punch of flavor.
- Crispy Fried Onions: This crunchy topping is the perfect finishing touch!
Step-by-Step Instructions
- Prep the Green Beans: Blanch them in boiling water for about 3 minutes, then plunge into ice water to keep them bright and crisp.
- Cook the Bacon: In a large skillet, crisp up the bacon until golden, then set aside on a paper towel to drain.
- Sauté the Veggies: Using the bacon drippings, cook the onions and mushrooms until caramelized, then add garlic and cook for another minute.
- Make the Sauce: Stir in heavy cream and chicken broth, then let it simmer until slightly thickened. Add shredded cheese and mix until melted.
- Combine Everything: Toss the green beans in the creamy sauce, then crumble in the crispy bacon.
- Bake to Perfection: Transfer to a casserole dish, top with crispy fried onions, and bake at 375°F (190°C) for 20 minutes until bubbling.

Chef’s Tips and Tricks
- Make It Ahead: Assemble the casserole a day before, then bake right before serving.

- Want More Flavor? A dash of smoked paprika or cayenne in the sauce adds just a hint of warmth.
Recipe Variations and Serving Suggestions
- Make It Vegetarian: Swap the bacon for smoked paprika and use vegetable broth for a meat-free version.
- Extra Cheesy: Try adding a handful of Gruyère or Parmesan to the sauce for an extra decadence.
- Pairing Ideas: Serve this casserole alongside roasted turkey, ham, or even a juicy steak for the ultimate meal.
FAQs
Can I use canned green beans? I recommend fresh or frozen for the best texture, but if you’re in a pinch, drain and rinse canned green beans before using.
How do I store leftovers? Keep refrigerated in an airtight container for up to 3 days. Reheat in the oven to keep the topping crispy.
Can I freeze this casserole? Yes! Assemble it without the fried onions, freeze, and add the topping just before baking.
