How to Make Low Carb Chicken Casserole: A Delicious Keto-Friendly Recipe
Step 1: Prep and Cook the Chicken
Start by heating olive oil in a skillet over medium-high heat, then brown your chicken cubes until they have a golden crust all around. This step locks in flavor and keeps the chicken juicy. Cooking in batches ensures even browning without crowding the pan, so take your time and set the browned pieces aside once done.
Step 2: Sauté the Vegetables
Using the same skillet, soften the chopped onion until it becomes translucent and sweet. Then, add the garlic and mushrooms, cooking until the mushrooms release their juices and brown just slightly, which adds a fantastic umami punch. Finally, toss in the broccoli florets and cook briefly until they turn a vibrant green and soften just enough to be tender but still crisp.
Step 3: Make the Creamy Binder
While the veggies are cooking, whisk together softened cream cheese and mayonnaise in a medium bowl until smooth. Add eggs one by one, beating thoroughly after each to create a silky, combined mixture. This creamy base not only binds everything but also infuses the casserole with a rich, luscious texture.
Step 4: Combine Flavors
To your creamy mix, stir in almond flour, Parmesan cheese, parsley, thyme, salt, and pepper. These ingredients bring body, flavor, and a subtle nutty crunch to the casserole. Gently fold in the cooked chicken and sautéed vegetables, keeping the mixture uniform without overworking it. If you desire extra moisture, stir in chicken broth here to keep everything wonderfully juicy.
Step 5: Bake to Perfection
Pour the cheesy chicken and veggie mixture into a greased 8×8 inch baking dish. Generously sprinkle the shredded cheddar and Monterey Jack cheese evenly on top. Bake in a preheated oven at 375°F (190°C) for about 25 to 30 minutes, or until you see the cheese melted, bubbly, and lightly golden. For safety and perfect doneness, ensure the chicken reaches an internal temperature of 165°F (74°C). Finally, let the casserole rest a few minutes before serving—this helps everything set beautifully.

Make Ahead and Storage
Storing Leftovers
After enjoying this delicious casserole, pack any leftovers into an airtight container and store in the refrigerator for up to 3 days. The flavors meld nicely overnight, making it even tastier the next day for an easy lunch or quick dinner.
Freezing
If you want to save this Low Carb Chicken Casserole: A Delicious Keto-Friendly Recipe for later, freezing is a great option. Cool the casserole completely, cover tightly with plastic wrap and foil, then freeze for up to 2 months. To thaw, transfer to the refrigerator overnight before reheating.
Reheating
Reheat leftovers gently in a microwave or oven at 350°F (175°C) until warmed through. Covering with foil in the oven helps prevent the top from over-browning while ensuring the inside stays creamy and moist. A quick stir halfway through reheating can redistribute the cheese and flavors evenly.
FAQs
Can I use frozen vegetables in this casserole?
Absolutely! Frozen broccoli and mushrooms can be used if fresh aren’t available, but be sure to thaw and drain excess moisture first to avoid a soggy casserole.
Is this recipe suitable for other low-carb diets besides keto?
Yes, this dish fits well into any low-carb eating plan thanks to its focus on protein, healthy fats, and non-starchy vegetables.
Can I substitute the chicken with another protein?
Definitely! Turkey breast or even cooked ground beef can swap in for the chicken, offering a similar texture and flavor base.
What can I do if I don’t have almond flour?
You can try crushed pork rinds or coconut flour as keto-friendly alternatives, but adjust the amount slightly since they absorb moisture differently.
How spicy is this casserole?
This recipe is mild by default, perfect for all palates, but you can easily add red pepper flakes or diced jalapeños to bring in some heat.

Instructions

- Add eggs: Incorporate the eggs one at a time into the cream cheese mixture, whisking thoroughly after each addition to ensure a smooth batter.
