Combining the flavors from a Kentucky Hot Brown, this Creamy Keto Turkey, Bacon, and Tomato Casserole is great for a cheesy dinner party entrée, a dish for your weekly meal plan, or your contribution to a potluck.  What can I say, some flavor combinations from classic sandwiches make the best casseroles.  The low carb part is just a bonus.

What You Need to Make this Cream Keto Turkey, Bacon, and Tomato Casserole

Equipment

  • Cutting Board
  • Chef’s Knife
  • Rimmed Baking Sheet
  • Wire Rack Insert for Rimmed Baking Sheet
  • Heavy Duty Aluminum Foil
  • Cheese Grater – If you need / want to shred your own cheese. 
  • Saucepan – Large enough to hold and comfortably stir about a quart of liquid volume. 
  • Induction Burner – Completely optional, but if you have one, making the Mornay sauce is a good time to use it.
  • Large Sauté Pan – Or Skillet with Lid
  • Rubber Scraper – Or other utensil for stirring
  • Fine Mesh Strainer – For straining the onion, cloves, and bay leaf out of the heavy cream.
  • Measuring Cups
  • Measuring Spoons
  • Medium Mixing Bowl
  • 9 x 13 inch Casserole Dish
  • Nonstick Cooking Spray

Ingredients

For the Mornay Sauce:

  • Heavy Cream
  • Onion (large onion)
  • Whole Cloves
  • Bay Leaf
  • Grated or Shredded Parmesan Cheese
  • Shredded Gruyère Cheese
Ingredients for Mornay Sauce

For the Casserole:

  • Thick-cut Bacon – Cooked and diced.  
  • Cooked Turkey – I buy the pre-cooked turkey breast at Sam’s Club and then just cube up what I need.
  • Cauliflower Rice – I like the 12 ounce bags when I can find them.  However, if your store only has 10 or 10.5 ounce bags then just use that. 
  • Chicken Broth or Stock – I recommend my Homemade Chicken+ Broth if you have the time and inclination.
  • Fire Roasted Diced Tomatoes – I use 2 (14.5-ounce) cans, drained.  You can use regular diced tomatoes if you can’t find the fire roasted ones.
  • Kosher Salt
  • Ground Black Pepper
  • Nutmeg – Freshly grated, if you can.
  • Paprika – I suggest Smoked Paprika if you have it. 
  • Dried Parsley
  • More Heavy Cream
  • Mornay Sauce – This is what you’ll have made with the ingredients listed above.
  • More Grated or Shredded Parmesan Cheese
  • More Shredded Gruyère Cheese

Getting Started with Making Creamy Keto Turkey Bacon and Tomato Casserole

This casserole part of this recipe comes together quickly.  However, there are two steps that I suggest you prep in advance to streamline your process. 

Cooking Bacon and Prepping the Turkey

The easy “advanced prep” step is cooking the thick-cut bacon.  To do so, you’ll start by lining a rimmed baking sheet with heavy duty aluminum foil and inserting a wire rack and preheating the oven to 400°F.  Just lay out the bacon strips on the wire rack and bake them at 400°F for 20 minutes.  Using a pair of tongs, you’ll flip them over and place them back in the oven for approximately another 10 minutes or until crispy.  The exact timing will depend on your oven and the thickness of the bacon.  

Once it’s nicely crisped (not burnt), you’ll want to remove it to a paper towel lined plate to soak up the extra grease.  Then you can cut it into bite sized pieces and set it aside.  

Lori Tip: I use kitchen shears to cut the bacon.

While the bacon is cooking, you can cut the cooked Turkey into bite sized cubes and set it aside. 

Making the Mornay Sauce

Because we’ll need a cup of Mornay Sauce, we’ll start by pouring 1 ⅓ cups of Heavy Cream into a small saucepan and adding ⅛ of a large onion, 4 whole cloves, and 1 bay leaf.  Now, you’ll bring the mixture just to a boil and then drop the heat to a simmer, stirring constantly.  You’ll need to allow it to simmer until it begins to thicken and is reduced by about ⅓ of a cup (about 10 minutes).  

Using a fine mesh strainer, you need to remove the onion, cloves, and bay leaf from the thickened cream.  Then you’ll pour the cream back into the saucepan and return it to a low medium heat.  

Next, we’ll stir continuously while adding 2 ounces of grated Parmesan cheese and 2 ounces of shredded gruyère cheese.  You need to keep stirring until the cheese has melted and is fully incorporated into the sauce.  Then you can remove it from the heat and set it aside.  

Assembling the Casserole

In a large sauté pan, you’ll combine 24 ounces of Cauliflower Rice, 1 cup of Chicken Stock or Broth, 29 ounces Fire Roasted Diced Tomatoes (2 cans), 1 teaspoon of Kosher Salt, 1 teaspoon of Ground Black Pepper, ½ teaspoon of freshly grated Nutmeg, ½ teaspoon Paprika (preferably Smoked), and ½ teaspoon of Dried Parsley.  Cook over medium heat until the liquid has evaporated (about 10 minutes).

Keeping the mixture on the heat, you’ll add 1 cup of Heavy Cream and 1 cup of the Mornay Sauce that you made.  Once those ingredients are incorporated, stir in 1 ounce of grated Parmesan Cheese and 4 ounces of Gruyere Cheese until they are melted.  

Finally, stir in all of the cubed Turkey and two thirds of the Bacon pieces.  You’ll sprinkle the saved Bacon pieces on top before baking.  

Then you can remove the pan from the heat and pour the mixture into a well greased 9×13-inch casserole dish.  

To top the casserole, sprinkle on the remaining 1 ounce of grated Parmesan Cheese, 2 ounces of shredded Gruyère Cheese, and Bacon pieces.

Baking this Creamy Keto Turkey, Bacon, and Tomato Casserole

At this point, you can either cool it completely and then store in the refrigerator until you’re ready to bake it or bake it immediately. 

To bake, you’ll preheat the oven to 350°F.  You will bake the casserole at 350°F for 30 minutes or until it’s bubbling and the cheese on top has melted.

Notes

  • Advanced Prep
    • Once everything is combined and poured into the 9×13-inch casserole dish and topped with cheese and bacon, you can either cool it completely and then store in the refrigerator until you’re ready to bake it or bake it immediately.
    • If you store it in the refrigerator, remove it from the fridge 30 – 45 minutes before baking.
      Alternatively, you can place the cold dish into the cold oven and then pre-heat them together. However, in this case, don’t start the clock on the bake time until the oven has come up to temperature.
