Nothing screams “American comfort food” like a tuna casserole! Invented about 80 years ago (wow), tuna casserole is still made for many families today. Sometimes, you just have to make something quick and filling for hungry mouths!. Each slice of this Keto tuna casserole has a layer of Low Carb shirataki noodles, thick and gooey cheese sauce, flakey canned tuna, and a crumbly pork rind topping. Add a side dish to make a full meal or use this recipe as the side course to a main meal.

How to Make It

Step 1

Make the cheese sauce first by combining heavy cream and butter in a saucepan on the stove. Heat the ingredients over low heat, and whisk them together until the butter melts. Without letting the cream reach a simmer, whisk cheddar cheese, salt, pepper, and garlic powder into the pot. Whisk until the cheese has melted and the cheese sauce comes together.

Step 2

Set the cheese sauce aside to cool down and thicken. Prepare the shirataki noodles next by following the directions on the packaging. You’ll likely need to drain the noodles and rinse them first. Then, cook them in boiling water on the stove for 2-3 minutes to tenderize them. Drain the noodles, and let them cool down for 5 minutes before continuing.

Step 3

After the shirataki noodles cool, add them to your pot of cheese sauce. Drain the canned tuna completely before stirring the tuna into the pot of noodles and cheese sauce. Then, stir the final amount of shredded cheddar cheese into the pot. It’s okay if the cheese melts a little bit, but you don’t want the cheese to melt completely yet.

Step 4

Pour and spread the tuna casserole into a glass baking dish and set it aside. Grind a bag of pork rinds in a blender or food processor, then measure out the amount you need listed in the ingredients. Spread the ground pork rinds across the top of the casserole.

Step 5

Turn on your oven’s broiler to high heat. Once the broiler is heated, add the casserole dish to the oven. Cook the casserole for approximately 15 minutes or longer. Look for golden brown edges all around the casserole dish, and the pork rinds should be darkened and golden. Cool the casserole for 5 minutes before slicing it for serving.
