Low Carb Steak Marinara Sauce Recipe

Keto steak marinara sauce is an easy keto freezer meal you can prepare quickly using your Instant Pot. It’s also a good way to use up leftover steak you might have from the night before. Pour this rich, tangy tomato sauce over your favorite keto pasta or cauliflower rice for a dinner you can throw together and serve within 30 minutes!
Leftover Steak
I’m always looking for ways to use up leftover proteins like steak so that I can recreate dinner into a new recipe without boring the family or myself with the same meals over and over again. This steak marinara recipe is a great way to use up extra steak you might have leftover from dinner.
Keto Meal Prep – Freezer Meals
One way to stay successful on the keto diet is to meal prep your food. Employ freezer meals in your meal prep tatics too. Both will make sure you have keto meals on hand when you get busy and don’t have time to cook.
This keto steak marinara sauce can be easily made during meal prep day or you can make it on a night that you have steak for dinner and are looking for a way to use up the leftover steak. Simply slice up the steak and add it to a freezer bag along with the rest of the ingredients. Store in the refrigerator to use the next night or pop in the freezer to cook later.
For an easy way to add your ingredients into a ziploc bag, use freezer bag holders to keep the bag upright. This way you don’t have to worry about your ingredients spilling out of the bag.

Low Carb Marinara Sauce
You have two options for sauce in this easy keto dinner recipe. You can add a keto approved marinara sauce or you can use canned tomato sauce. Just make sure you are selecting brands that don’t contain any additional sugars or carbohydrates.
My favorite keto brand pasta sauce is by Rao’s. They have a marinara sauce for sensitive diets – meaning that it doesn’t contain any garlic or onions that may upset some sensitive stomaches. This brand of sauce only has 5 grams net carbs per 1/2 cup.

How to Cook Keto Steak Marinara on the Stove Top
If you don’t have an Instant Pot or pressure cooker, you can still make this easy keto freezer meal by cooking it up on the stove top. Just add your thawed freezer bag to a skillet and heat over medium high heat until sauce is bubbling and steak is cooked through.

Keto Pasta
This Italian steak marinara is begging to be poured over something. Of course you can go with a traditional keto food like cauilfower rice or zucchini noodles (also called zoodles). Another option is to try keto noodles.
There are different types of keto noodles you can buy. The three most popular types are:
- Shirataki Noodles – These noodles are zero carbs and are made out of konjac yam and contain primarily water and glucomannan, a water soluble fiber.
- Hearts of Palm Noodles – These keto noodles are made out of hearts of palm and are very low in carbs. They don’t have a strange smell or chewy texture like shiraki noodles.
- Low Carb Wheat Based Pasta – The Low Carb Bread Company makes a keto approved pasta noodle that contains wheat protein. These aren’t gluten free but it’s a great alternative when you want authentic noodles.
