What Are Fajitas

Fajitas are a classic Tex-Mex dish where meat is seasoned and grilled along with onions and bell peppers. Obviously this is not the traditional way of making fajitas since a slow cooker or Instant Pot is involved but the flavor is still there!

How To Make Steak Fajitas In The Slow Cooker

Making steak fajitas in the slow cooker or Instant Pot is very easy. If you use the slow cooker, this fajitas recipe is a true set-it-and-forget-it recipe.

Slow Cooker

1. Add all ingredients to the slow cooker. Stir to mix well.
2. Cook HIGH 2-3 hours, LOW 4-6.

Instant Pot

1. Turn on the pressure cooker and select sauté. Once hot add oil and beef to the pot. Cook 2-4 minutes or until beef is browned. Remove beef & set aside. Drain excess grease if needed.
2. Add onions& bell peppers. Cook 3-5 minutes or until vegetables are soft. Pour in broth or water and deglaze the bottom of the pressure cooker by scraping all the bits off with a wooden spoon.
3. Add beef back to the pot along with diced tomatoes and fajita seasoning. Stir to mix well.
4. Close lid and seal valve. Set high pressure for 9 minutes. When cooking time is complete, quick release the pressure. Stir & serve.

What Type Of Beef To Use

I used a 2 pounds of flank steak that I sliced into strips. The beauty about the slow cooker or Instant Pot is that you can use your preferred cut of beef in this recipe. If not flank steak, other suggestions include sirloin, skirt steak, flat iron, chuck roast, rump, flank steak, beef stew meat, etc. You can substitute chicken or pork instead of beef if you like. Heck I have evenmade these fajitas using a large turkey breast. The concept stays the same, just swap out the protein.

How To Serve Slow Cooker Fajitas

Traditionally fajitas are served in corn or flour tortillas. I believe you should serve these fajitas according to your dietary restrictions. My go-to is lettuce wraps. Other suggestions are tortillas or over rice (regular, brown, or riced cauliflower). You can also use this as filling for burritos or even enchiladas. Popular garnishes for fajitas include cheese, guacamole, lettuce, salsa, sour cream, etc.

FAQs & Tips

• In the recipe box you will find my go-to homemade fajita seasoning. It’s equivalent to 1 store-bought packet.
• Store leftover fajitas in an air-tight container in the refrigerator for up to 4 days.
• The vegetables in this recipe are listed are 2 bell peppers and 1 large onion. I usually use 1 green bell pepper and 1 red one to be fancy. You can use 2 bell peppers of your choice. For the onions, I have used red onion, yellow onion, and white onion and I seriously don’t have a preference.
• I used a 6-quart slow cooker /Instant Pot.
