Introduction

This Low-Carb Keto Green Bean Casserole offers a delicious twist on the classic comfort food favorite, perfect for those watching their carb intake. Creamy, savory, and topped with crispy bacon, it’s sure to become a holiday or weeknight favorite.

The image shows a black cast iron skillet filled with green bean casserole. The dish has three main layers: a base layer of green beans mixed with a creamy white sauce and sliced mushrooms, topped with a crunchy brown crumb-like layer. The green beans are bright green, and the mushrooms appear soft and cooked. The brown crumb topping looks evenly spread over the green beans, adding texture contrast. A dark silver spoon rests inside the skillet on the left side. Around the skillet, there are three white bowls—one with pale yellow mashed potatoes, one with light golden stuffing, and one with dark red cranberry sauce with a spoon in it. The setting is on a white marbled surface with orange and red fall leaves and a small vase of dried orange flowers on the left. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

6 slices bacon
2 cups mushrooms (sliced)

1 cup onion (diced)
2/3 cup half-and-half

1/3 cup 2% milk
1/4 cup full-fat cream cheese

1 1/4 teaspoons sea salt
1/4 teaspoon pepper
1 pound green beans (trimmed)

Instructions

Step 1: Preheat the oven to 350°F and heat a large skillet over medium heat.
Step 2: Cook the bacon in the skillet until golden brown and crispy, about 4 minutes per side. Transfer to a paper towel-lined plate to drain excess fat. Discard most of the bacon fat in the pan, leaving about 1 tablespoon.
Step 3: Increase heat to medium-high and add the sliced mushrooms and diced onion to the skillet. Cook, stirring occasionally, until the vegetables are golden brown, about 3 minutes.

Step 4: Add half-and-half, milk, cream cheese, sea salt, and pepper to the skillet. Bring to a boil, stirring constantly. Continue boiling until the mixture begins to thicken, about 4 minutes.
Step 5: Reduce heat to medium and cook, stirring occasionally, until the sauce reaches a thick consistency similar to condensed soup, about 7 to 8 minutes.
Step 6: While the sauce thickens, bring a large pot of salted water to a boil. Add green beans and cook until just fork-tender, about 7 to 8 minutes. Drain and pat dry to remove excess water.

Step 7: Stir the green beans into the sauce until well coated. Transfer the mixture to an 8×8-inch baking pan, pressing it evenly.
Step 8: Bake in the preheated oven until bubbly, about 15 to 20 minutes.
Step 9: While baking, pulse the cooked bacon in a food processor until crumbly. Sprinkle the bacon crumbs over the casserole and bake an additional 5 minutes.

Step 10: Serve immediately and enjoy your creamy, keto-friendly green bean casserole.

Tips & Variations

For extra creaminess, use full-fat heavy cream instead of half-and-half and 2% milk.
Try adding a pinch of garlic powder or fresh thyme to the sauce for additional flavor.

Swap out the green beans for asparagus or broccoli for a different low-carb vegetable option.
Make vegetarian by omitting bacon and topping with toasted almonds or fried onions made from almond flour.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 300°F until warmed through, about 10-15 minutes, to maintain a crispy topping. Avoid microwaving to keep texture intact.
