The most requested recipe in my house these last few months have been garlic steak bites. So after serving them with zucchini noodles about a dozen times, I wanted to change it up. I love eating steak with mashed potatoes and some greens, so I created a low carb version of my steak meal.

Is steak good for meal prep?

Yes, I really enjoy making steak meal prep recipes. Steak cooks fast and also reheats well after it’s been in the refrigerator. It’s also really filling making it a great high protein meal.

I used New York strip steak for this recipe. You can also use ribeye or top sirloin steak.

To sear the steak, let the steak cook for a few minutes on each side before flipping to develop a golden sear.

I seasoned the steak with soy sauce. It flavors the steak, adds some color and reduces into a thick coating around the steak. If you do not wish to use soy sauce, you can also season with salt.

Mashed Cauliflower

For this recipe, I pair the steak bites with mashed cauliflower which is a lot like mashed potatoes but low-carb and a lot healthier.

  • I made my mashed cauliflower with a food processor.
  • Cauliflower rice is steamed until soft and then mashed with parmesan cheese and sour cream for a creamy mash.
  • You can add herbs or other seasonings to change up the flavor of the mashed cauliflower.

Vegetable Options

I usually like serving my beef with broccoli, bell peppers, string beans, or spinach. For the meal prep, I served mine with sautéed spinach. You can also serve this dish with my garlic mushrooms.

Reheating Tips

  • I reheat my meal preps in the microwave.
  • To prevent overcooking the steak during reheating, you can initially cook the steak to a medium rare.
  • You can also adjust your microwave cooking power. Instead of cooking at full power, set it to around 50% power, which should heat your steak without cooking it too much.

  • I use these Meal Prep Containers*
  • Instead of cauliflower rice, you can also use a large head of cauliflower, cut into bite-sized florets.
  • You can omit the soy sauce and season steak with just salt. Do not do a direct 1:1 substitution. Just season lightly with salt, as needed.
  • To prevent overcooking the steak during reheating, you can initially cook the steak to a medium rare.
