Update Note:

I’ve made a small update to the cooking method to help ensure extra tender chicken, especially with today’s leaner cuts. The ingredients and flavor you love are unchanged.

I saw a recipe video online for Chicken Lombardy that looked amazing. Although it wasn’t keto-friendly, I knew it could be a fabulous keto dish with a couple of tweaks. Even though I’m not too fond of actual mushrooms, I do like mushroom-flavored gravy and mushroom-flavored sauces. However, you can bet your bottom dollar I will pick out every stinking mushroom before taking one bite. (I might be a tad bit picky.)

Chicken Lombardy is sometimes called creamy chicken Lombardy or baked chicken Lombardy and is known for its rich mushroom-cream sauce and melted cheese topping. However you name it, this version is a low-carb, keto-friendly chicken dinner that feels comforting and doable for busy weeknights.

Ingredients:

  • Chicken breasts – Use thinly cut, boneless, skinless chicken breasts so they cook quickly and don’t dry out.
  • Heavy whipping cream – This is what makes the sauce creamy and comforting without adding carbs.
  • Chicken broth – Chicken broth gives the sauce that savory, cozy flavor and keeps everything from feeling heavy.
  • Xanthan gum – This is just to help the sauce thicken; you can leave it out if you want it a little thinner.
  • Grated Cheeses –I always grate my own cheese because it melts better and makes the sauce smoother.
  • Mushrooms – The mushrooms add a lot of flavor to the sauce, even if you’re the type who picks them out like I am.
  • Butter Butter adds richness and helps everything cook up just right.
  • Seasonings, Onion, & Garlic –These are simple, but they’re what make this dish actually taste good.

How to make this KETO CHICKEN LOMBARDY RECIPE

Step 1: Melt two tablespoons of butter in a large nonstick or cast-iron skillet. Sauté the mushrooms, garlic, and onions over medium-high heat for about 10 minutes. The onions should be translucent, and the mushrooms tender. Remove the veggies from the skillet and set them aside.

Step 2: Melt butter in the same cast-iron skillet. Sear the chicken breasts for 2–3 minutes per side, just until lightly golden. Do not cook the chicken through. It will finish cooking in the oven.

Step 3: After removing the chicken, return the mushroom mixture to the cast-iron skillet. Add the chicken broth, heavy whipping cream, and salt and pepper. Cook on medium-high heat for about 5 minutes, stirring continuously. 

Step 4: Turn the burner off and sprinkle the xanthan gum on top (optional). Allow the sauce to thicken. This should only take five to 10 minutes. It will still be a little bit broth-y.

Step 5: Once it has reached the desired thickness, spoon the sauce over the chicken in the casserole dish.

Step 6: Sprinkle the parmesan cheese over the chicken, then the mozzarella. Top with Italian seasoning.

Cover loosely with foil and bake at 400°F for 10 minutes. Remove the foil and continue baking for 8–10 minutes, or until the cheese is melted and bubbly and the chicken reaches 165°F. For a more golden top, move the dish to the top rack and broil for 1–2 minutes, watching closely.

 Tip: For tender chicken, avoid over-searing it in the skillet. It should be lightly browned but not cooked through before baking.

FAQ’S

How do I know which chicken to buy?

When making this keto Chicken Lombardy recipe, you will want thinly sliced chicken breasts. They will need to be lightly browned in the skillet and then finished gently in the oven. Thicker pieces will take longer to bake. If you can find thin chicken cutlets, that is ideal. However, if you cannot, here are three other options.

  1. Slice the chicken breasts lengthwise into two pieces. 
  2. Use a meat mallet to pound and thin them out. You want them to be about ¼-inch thick. Cover it with plastic wrap to prevent chicken juice from splattering everywhere. 
  3. If you don’t mind the thicker cuts, you can use thighs, breast tenderloins, or any other cut of chicken. You will need to adjust the cooking time slightly depending on the thickness. Thicker cuts may benefit from a longer bake at a lower temperature to stay tender.

Can I use chicken thighs instead?

Yes. Boneless, skinless chicken thighs are an excellent option for this recipe and tend to stay extra tender. If using thighs, sear them just until lightly browned, then bake uncovered at 400°F for 20–22 minutes, and broil briefly at the end if needed for color.

Can I use olive oil in place of butter?

Yes. You can use olive oil, avocado oil, or any other oil you would like. However, I like the rich, silky quality butter adds to this dish.

Can I make Chicken Lombardy ahead of time?

This is great right out of the oven, but it also makes good leftovers. Store it covered in the fridge for up to 3 days, and reheat gently in the microwave or oven so the chicken stays tender and the sauce doesn’t separate.

Why did my chicken turn out tough?

Chicken usually turns out tough when it’s overcooked, which can happen if it’s seared too long in the skillet or baked at too high a temperature for too long. That’s why this recipe lightly browns the chicken first, then finishes it gently in the oven so it stays tender and juicy. Using thinner cutlets or chicken thighs also makes a big difference.

This dish is comforting, filling, and simple enough for busy nights. I never imagined I would love this Keto Chicken Lombardy as much as I do, but it tastes restaurant-quality without all the effort.

What do I serve with it?

We usually serve this with roasted asparagus or Brussels sprouts, and a simple salad on the side. Nothing fancy, just enough to round out the meal.

Notes

Chicken Thigh Variation
You can substitute boneless, skinless chicken thighs for extra tenderness.
  • Use 2½ lbs boneless skinless chicken thighs
  • Sear 2 minutes per side (they brown quickly)
  • Bake uncovered at 400°F for 20–22 minutes
  • Broil only if additional browning is desired
Thighs are more forgiving and stay juicy even if slightly overcooked.
Additional Tips:
  • Avoid over-searing the chicken. It will finish cooking in the oven.
  • Xanthan gum is optional and does not affect flavor.
  • Freshly grated cheese melts more smoothly.

  1. This is Ahhhmazing! I loved the flavors and I even ate the mushroom(which I normally pick out)
    I grilled some asparagus, lightly, and put that on top of the chicken before the sauce and cheeses.
    The result was so good! The next time I will cut the asparagus into small pieces and serve the whole dish over riced cauliflower.
    Thank you from me and a big heap of gratitude from my husband!

  2. 5 stars
    WE loved this dish and definitely will make it again. I changed this slightly by adding some cooked, diced bacon and spinach to the sauce just long enough to have the spinach wilt. Then I followed the remainder of the recipe. Delicious, low carb.

  3. I made this with a big boneless chicken breast that my husband had cooked on the grill. I just sliced it , sautéed my veggies, made the sauce, topped with cheese and baked! It was really good, next time I will add in some sautéed green beans or broccoli, maybe some chopped bacon too! Very good!!

  4. 4 stars
    This dish was very good. However, we felt the chicken was on the tough side. Is it possible that 450° is too hot? I will try it again and maybe turn the temp down a bit.

    1. There are so many variables that can affect the chicken. Different ovens perform differently, the size of chicken breasts, etc. My best advice is to use a meat thermometer and pull it out of the oven a few degrees before it hits 165 degrees. Let me know how it turns out next time. Glad y’all enjoyed it!

  5. I love your recipes. The flavor was fantastic. I just can’t seem to get chicken breasts to come out of the oven with a nice texture. Chicken was rubbery, tough, and chewy. I did bake longer than recipe recommended until internal temp reached 165. When I looked online, it said chicken would be tough if it was undercooked or overcooked. Is there a trick to getting this right?

    1. Chicken can be tough to nail. Not cooked long enough and it is rubbery and I feel like I will die of food poisoning if I tough it! lol. Too long and it is a tough dinner. Literally. My best advice is watch the internal temp and take out of the oven about 4-5 degrees before it is done. It should finish cooking once out of oven. Bonus tip. Always slice it against the grain if the meat.

  6. 5 stars
    Family absolutely loved it! We’ve made several recipes from Kasey’s site and this was among the best. A couple thoughts regarding other reviews:
    * The chicken was a little tough but not problematic, iMHO.
    * Some folks talked about adding other veggies to it, and I think that would definitely work.
    * My wife is a huge fan of mushrooms, her only criticism was that this didn’t have enough. If you are a mushroom fan, consider adding another four or eight oz of mushrooms.
