Supreme Green Bean Casserole | Low Carb, Keto, Gluten-Free

Introduction

Supreme Green Bean Casserole has all the rich, nostalgic flavor of classic holiday comfort food, but in a low carb, keto-friendly, and gluten-free package you can enjoy year-round. Packed with vibrant green beans, a luscious, creamy sauce, and a satisfyingly crisp topping, this dish pleases everyone at the table—whether you’re following a special diet or just craving hearty, wholesome flavor.

Why Supreme Green Bean Casserole Stands Out

This recipe is a game-changer because it swaps out the traditional canned soups and fried onions for a fresher, healthier take while maintaining that irresistible creamy-crispy combination. Perfect for family dinners, holiday gatherings, or meal prep, this version is quicker, cleaner, and more flavorful than ever—without compromising your health goals.

The Secret to Creamy, Dreamy Low Carb Sauce

Achieving that signature creamy interior without the carbs is simpler than you think. Heavy cream and cream cheese form a decadent sauce, flavored with sautéed mushrooms, garlic, and onion for depth. A pinch of freshly grated nutmeg and a touch of black pepper bring everything together for a gourmet taste with familiar comfort.

How to Assemble Your Supreme Green Bean Casserole

Start by blanching fresh green beans so they retain a tender bite and vibrant color. Layer them in a casserole dish, spread your homemade sauce generously on top, and finish with a crunchy, gluten-free topping of almond flour, shredded parmesan, and toasted sliced almonds. Baking brings everything together into the ultimate cozy casserole.

Serving Suggestions for Maximum Flavor

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a medium casserole dish.
2. Blanch green beans in a large pot of boiling salted water for 4-5 minutes until just tender and bright green. Drain and immediately transfer to a bowl of ice water. Drain again, pat dry, and set aside.
3. In a large skillet, heat olive oil or butter over medium heat. Add onions and sauté for 1-2 minutes. Add garlic and mushrooms, cooking for an additional 4-5 minutes until softened and moisture has released.
4. Lower heat and stir in cream cheese until melted and combined. Add heavy cream, half the parmesan, black pepper, nutmeg, and ½ teaspoon salt. Simmer 2-3 minutes until creamy and thick. Remove skillet from heat.
5. Gently toss green beans with the sauce and transfer mixture into prepared casserole dish.
6. Mix almond flour, sliced almonds, and remaining parmesan with ¼ teaspoon salt. Sprinkle evenly over casserole.
7. Bake uncovered for 20-25 minutes, or until top is golden and casserole is bubbling. Let stand 5 minutes before serving. Garnish with fresh parsley if desired.
