Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

boneless, skinless chicken breasts
olive oil or butter
fresh mushrooms (sliced)
fresh spinach
garlic cloves (minced)
heavy cream
cream cheese
shredded mozzarella or provolone
grated parmesan cheese
salt
pepper
Italian seasoning or thyme (optional)

Directions

I preheat the oven to 375°F (190°C) and lightly grease a baking dish.
I season the chicken breasts with salt, pepper, and a sprinkle of Italian seasoning.
In a skillet, I sauté sliced mushrooms in olive oil or butter until golden, then add garlic and cook until fragrant.
I stir in the fresh spinach and let it wilt down, then mix in the cream cheese and heavy cream until smooth.
I remove the skillet from the heat and stir in half the mozzarella and a bit of parmesan.
I place the chicken in the baking dish, then pour the creamy spinach-mushroom mixture over the top.
I sprinkle the rest of the cheese on top and bake uncovered for 25–30 minutes, or until the chicken is cooked through and the top is bubbly and golden.
I let it rest for a few minutes before serving to let the sauce thicken slightly.

Variations

Sometimes I swap the chicken breasts for boneless thighs for extra juiciness. I’ve also added chopped sun-dried tomatoes or a spoonful of pesto to the sauce for a Mediterranean twist. For even more low-carb vegetables, I toss in diced zucchini or cauliflower rice. And when I want a stronger cheese flavor, I use aged white cheddar or gouda instead of mozzarella.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, I use the oven at 350°F (175°C) for about 15 minutes, or microwave individual portions for 1–2 minutes until hot. The sauce thickens after chilling, but I just stir in a splash of cream before reheating if I want to loosen it up.

FAQs

Can I use frozen spinach?

Yes, I’ve used thawed and drained frozen spinach in a pinch. I make sure to squeeze out all the excess moisture so the sauce doesn’t get watery.

What mushrooms work best?

I usually use cremini or white button mushrooms, but shiitake or baby bella mushrooms add a richer flavor if I have them on hand.

Can I make this dish ahead of time?

Absolutely. I assemble everything ahead, cover it, and refrigerate it. Then I bake it when I’m ready—just add 5–10 extra minutes to the bake time if it’s going in cold.

Is this keto-friendly?

Yes, it’s perfect for keto. It’s high in protein and fat and very low in carbs, especially if I use full-fat dairy.

What sides go well with this dish?

I usually serve it with a simple green salad, roasted broccoli, or sautéed green beans. Cauliflower mash also makes a great pairing if I want a more filling meal.

Conclusion

This chicken, spinach, and mushroom low-carb oven dish is a creamy, cheesy, and delicious way to enjoy a satisfying dinner without the carbs. I love how easy it is to make and how versatile the ingredients are. Whether I’m sticking to a low-carb diet or just looking for a healthy, flavor-packed meal, this one always earns a spot on my dinner table.
