Step by Step Instructions for Keto Garlic Mushroom Chicken Casserole
Heat Your Oven
Set your oven to 350°F and let it warm up while you prep everything else. This gives it time to reach the right temperature so your casserole cooks evenly.
Sauté The Mushrooms And Garlic
Pour 1 tablespoon of olive oil into a skillet and turn the heat to medium. Once the oil is warm, add the following to the pan:
Cook these together for about 5 to 7 minutes, stirring occasionally, until the mushrooms soften and release their moisture.
The garlic should smell fragrant when it’s ready.
Combine Everything In A Bowl
Take a large mixing bowl and gather all your remaining ingredients together.
Add the following to the bowl:
Stir everything together until the chicken and mushrooms are coated evenly in the cream and cheese mixture.
Transfer To Your Casserole Dish
Pour the entire mixture into a casserole dish, spreading it out so it sits in an even layer.
This helps it cook uniformly in the oven.
Bake Until Golden
Place your casserole in the oven at 350°F for 25 to 30 minutes.
Watch for the edges to bubble and the top to turn golden brown. Once it reaches that point, take it out and let it rest for a couple of minutes before serving.

FAQs
Can I use fresh garlic instead of garlic powder?
Yes, fresh garlic works great. Sauté about 4-5 minced cloves with the mushrooms in step 3, then skip the garlic powder in the mixture.
What type of mushrooms should I buy?
Any variety works-cremini, button, or shiitake all taste delicious. Pick whichever ones are available at your grocery store.
Do I need to cook the chicken first?
Yes, the chicken needs to be cooked before mixing it in. Use rotisserie chicken, leftover cooked chicken, or cook chicken breasts in the skillet before adding mushrooms.
Can I use a different cheese?
Heavy cream and cheddar are traditional, but parmesan, mozzarella, or a blend work fine too.
What if the casserole isn’t bubbly after 25 minutes?
Just give it a few more minutes in the oven. Every oven runs differently, so check around the edges-when it bubbles there, it’s done.
Is this dish actually keto-friendly?
Yes, it’s low in carbs and high in fat and protein, which fits keto perfectly. Just watch portion sizes and track what fits your daily carb limit.

Ingredients
Proteins and Dairy:
- 2 cups cooked chicken, shredded
- 1 cup heavy cream
- 1 cup shredded cheese
Vegetables and Aromatics:
- 1 cup mushrooms, sliced
- 3 cloves garlic, minced
Cooking Fats and Seasonings:
- 1 tablespoon olive oil
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and pepper to taste
Instructions
- Get your oven warming to 350°F so it’s ready when you need it.
- Pour 1 tablespoon of olive oil into your skillet and let it heat over medium temperature for about 1 minute.
- Add your 3 minced garlic cloves to the hot oil and let them cook for 30 seconds until fragrant.
- Toss in your 1 cup of sliced mushrooms and cook them at medium heat for about 5 minutes, stirring occasionally until they soften and release their moisture.
- Combine your 2 cups of shredded cooked chicken with the sautéed mushroom mixture in a large mixing bowl.
- Fold in your 1 cup of heavy cream, 1 cup of shredded cheese, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and season everything with salt and pepper to your liking.
- Transfer the entire mixture into your casserole dish, spreading it evenly so it cooks uniformly.
- Slide your casserole into the 350°F oven and bake for 25 to 30 minutes until the top turns golden and the filling bubbles at the edges.
Notes
- Brown your mushrooms properly before mixing them in, as they release moisture during baking and can make the casserole watery if they’re not cooked down first.
- Use rotisserie chicken to save time, or shred leftover cooked chicken from any meal to keep prep quick and simple.
- If your casserole seems too thick after baking, the heavy cream may have reduced more than expected, so add a splash of chicken broth to loosen it up before serving.
- For a dairy-free version, swap the heavy cream for full-fat coconut milk and use dairy-free cheese, though the flavor will shift slightly from the original.
