Gather Your Ingredients for Creamy Low Carb Chicken Casserole

Alright, let’s get our kitchen prepped! For this amazing Creamy Low Carb Chicken Casserole, you’ll want to round up these goodies:

For the Casserole:

  • 1/4 cup butter: Just good old unsalted butter, nothing fancy needed here!
  • 1 pound chicken: I like to cube it up into bite-sized pieces, about 1-inch is perfect.
  • 5 ounces mushrooms: Slice ’em up! Cremini or white button mushrooms work great.
  • 1/2 cup onion: Finely chopped so it blends in nicely.
  • 1 tablespoon fresh thyme: Or if you’ve only got dried, 1 teaspoon will do the trick.
  • 1 teaspoon sea salt: To bring out all those delicious flavors.
  • 1/2 teaspoon fresh ground black pepper: Give it a good grind!
  • 1 teaspoon garlic: Minced, because garlic makes everything better.
  • 8 ounces frozen chopped spinach: Make sure it’s thawed and squeezed super dry!
  • 1 cup chicken broth: Use a good quality one for the best flavor.
  • 8 ounces cream cheese: Full-fat is best for that super creamy texture.

For the Topping:

  • 1 cup shredded gruyere cheese: Oh, this cheese gets so bubbly and delicious when it bakes!

Step-by-Step Guide to Making Your Creamy Low Carb Chicken Casserole

Alright, let’s get this deliciousness going! Making this Creamy Low Carb Chicken Casserole is way easier than you think. Just follow these simple steps, and you’ll have a fantastic meal on the table in no time:

  1. Preheat your oven: Get that oven fired up to 350°F (175°C). You want it nice and toasty before your casserole goes in.
  2. Melt the butter: Grab a large skillet and melt your butter over medium-high heat. It should sizzle nicely!
  3. Brown the chicken: Toss in your cubed chicken and cook it for about 5 minutes, just until it gets nicely browned on all sides. Don’t cook it through yet! Scoop the chicken out and set it aside for a moment. Maybe you’ll be inspired by how tasty this chicken prep looks, just like in this Keto Chicken Broccoli Casserole recipe.
  4. Sauté the veggies: Now, add your sliced mushrooms, chopped onion, fresh thyme, sea salt, and pepper to the same skillet. Cook these beauties for about 6 minutes, stirring sometimes, until they start to soften up and smell amazing. This step is key, much like in other amazing chicken and mushroom dishes you can find advice on, like this Keto Chicken Mushroom Casserole.
  5. Add the garlic and spinach: Toss in your minced garlic and the thawed, well-drained chopped spinach. Cook for another 2 minutes, just until the garlic is fragrant. We don’t want that garlic to burn!
  6. Make it creamy: Pour in the chicken broth and add your cream cheese. Stir it all up until the cream cheese melts and creates a luscious, creamy sauce. This is where the magic starts happening!
  7. Combine everything: Stir your browned chicken back into the creamy sauce in the skillet. Get it all coated and mixed together.
  8. Assemble the casserole: Pour this glorious chicken mixture into your casserole dish. Spread it out evenly.
  9. Top with cheese: Sprinkle the shredded gruyere cheese all over the top. Get it right to the edges so you get that glorious, bubbly crust.
  10. Bake to perfection: Pop that casserole dish into your preheated oven and bake for 25 to 30 minutes. You’re looking for that cheese to be melted, golden brown, and bubbly. The whole kitchen will smell incredible!

  • Let it rest: This is important! Once it’s out of the oven, let your Creamy Low Carb Chicken Casserole sit for about 5 minutes. This little rest helps everything settle and makes it easier to serve. Trust me, it’s worth the wait!
  • Tips for the Best Creamy Low Carb Chicken Casserole

    Okay, so you’ve got the recipe, but here are a few little secrets from my kitchen to yours to make this Creamy Low Carb Chicken Casserole absolutely sing. As Mark Williams, The Keto Performance Chef, I’ve learned a few tricks along the way that really elevate a dish. First off, quality ingredients make a huge difference. Use fresh mushrooms if you can; they have so much more flavor than canned ones. And don’t skimp on draining that spinach! If it’s too watery, your casserole might end up a bit soupy, and we want it perfectly creamy, not watery. Also, when browning the chicken, don’t overcrowd the pan. Cook it in batches if you need to, so it gets a nice sear instead of just steaming. This little step adds a depth of flavor that’s hard to beat!

    Ingredient Notes and Substitutions

    You know, the beauty of this Creamy Low Carb Chicken Casserole is how forgiving it is! If you don’t have gruyere cheese on hand, don’t sweat it. Monterey Jack, a sharp cheddar, or even a good mozzarella would be delicious melted on top. For the herbs, if fresh thyme isn’t your jam or you can’t find it, a pinch of dried rosemary or even a little sage works wonderfully. And about that chicken? Boneless, skinless thighs are fantastic here too; they stay extra moist!

    Serving Suggestions for Your Casserole

    This Creamy Low Carb Chicken Casserole is pretty much a complete meal on its own, but if you want to round out your plate, think simple and low-carb! A big fresh salad with a zesty vinaigrette is always a winner. Steamed broccoli or green beans with a sprinkle of butter are also fantastic.

    Storage and Reheating

    Leftovers of this glorious Creamy Low Carb Chicken Casserole? YES, please! To store, just pop any extra into an airtight container and pop it in the fridge. It should keep beautifully for about 3 to 4 days. When you’re ready to reheat, gently warm it up on the stovetop over low heat, or microwave individual portions until just heated through. If you’re reheating a larger amount, a low and slow bake in the oven (around 300°F or 150°C) also works wonders to keep it from drying out. Some folks even find it freezes pretty well, though I always think it’s best enjoyed fresh!

    Frequently Asked Questions about Creamy Low Carb Chicken Casserole

    Got questions about this super yummy Creamy Low Carb Chicken Casserole? I’ve got you covered! Here are a few things people often ask:

    Can I add other vegetables to this casserole?

    Absolutely! This recipe is super flexible. Feel free to toss in some chopped cauliflower florets, diced bell peppers (any color!), or even some extra broccoli. Just make sure they’re chopped small enough to cook through in the time frame, or you might want to give them a quick steam or sauté beforehand. It’s a fantastic way to sneak in more veggies!

    Is this casserole freezer-friendly?

    Yes, it totally is! This Creamy Low Carb Chicken Casserole freezes remarkably well. Once it’s cooled completely, portion it out into freezer-safe containers or wrap individual servings tightly. It can typically be stored in the freezer for up to 2-3 months. Perfect for those times you need a quick, healthy meal in a pinch!

    What makes this casserole low carb?

    Great question! The “low carb” magic happens because we’re skipping the usual carb-heavy fillers like pasta, rice, or potatoes. Instead, we’re focusing on protein from the chicken, healthy fats from the cream cheese and butter, and fiber and nutrients from the spinach and mushrooms. The cheese topping adds flavor and richness without a carb overload. It’s all about smart ingredient choices that keep you satisfied and on track with your low-carb goals!

    Can I use chicken thighs instead of chicken breast?

    Oh, for sure! Chicken thighs are actually a fantastic choice for this casserole. They tend to be a bit more forgiving, staying super moist and flavorful even when baked. Just make sure to trim any excess fat before cubing them. The cooking time might be just slightly longer, but the result is incredibly tender chicken!

    Nutritional Information

    Now, let’s talk numbers! For this delightful Creamy Low Carb Chicken Casserole, you’re looking at roughly 389 calories per serving. It packs a good punch of protein at about 18 grams, with a lean 6 grams of carbs and around 34 grams of fat. Remember, these are estimates, and your exact values might dance around a bit depending on the exact brands and ingredients you use, but this gives you a great idea of what you’re working with!
