Step‑by‑Step Instructions for Instant Pot Steak Fajita Bowls
Step 1: Prepare the Steak
Slice the flank steak into thin strips, aiming for about 1/4 inch thick to ensure tenderness. In a mixing bowl, combine the steak with chili powder, salt, cumin, garlic powder, onion powder, and coriander. Toss until each piece is well-coated with the spices, allowing for that rich, flavorful profile that makes your Instant Pot Steak Fajita Bowls truly irresistible.
Step 2: Sauté the Steak
Select the sauté mode on your Instant Pot, and heat the avocado oil. Once hot, carefully add the seasoned steak to the pot, letting it brown for about 1-2 minutes. Stir occasionally to avoid burning, and look for a nice sear on the edges. Once browned, cancel the sauté function, preparing for the flavorful blend of vegetables to follow.
Step 3: Add the Vegetables
With the steak still in the pot, add the sliced green and red bell peppers, jalapeño, and diced red onion. Then, mix in the minced garlic for a pop of fresh flavor. Pour in the beef broth and stir in the tomato paste, ensuring all ingredients are well distributed. This colorful medley will infuse your Instant Pot Steak Fajita Bowls with vibrant taste and texture.
Step 4: Pressure Cook
Secure the lid on your Instant Pot and set the steam valve to sealing. Adjust the pressure setting to high and cook for 7 minutes. As it cooks, the fragrant aromas of steak and peppers will fill your kitchen, making your mouth water in anticipation of those delicious flavors melding together.
Step 5: Release the Pressure
Once the cooking time is complete, carefully perform a quick release by moving the steam valve to venting. Take caution, as hot steam will escape. After the pressure indicator drops, open the lid to reveal the tender, juicy steak alongside perfectly sautéed vegetables—the essence of your Instant Pot Steak Fajita Bowls.
Step 6: Serve and Enjoy
Scoop the steak and veggie mixture generously over a bed of cauliflower rice or fresh salad greens. Feel free to top your bowls with avocado, sour cream, or your favorite toppings for extra flair. Each bite will be a delightful fusion of flavors, showcasing the ease and convenience of your Instant Pot Steak Fajita Bowls!

Make Ahead Options
These Instant Pot Steak Fajita Bowls are a fantastic meal prep option for busy weeknights! You can slice the flank steak and toss it with the seasonings up to 24 hours in advance, storing it in an airtight container in the fridge. The bell peppers, onion, and jalapeño can also be sliced ahead of time and kept in the refrigerator for up to 3 days to maintain their crispness. When you’re ready to cook, simply sauté the marinated steak for 1-2 minutes, add the prepped vegetables, and proceed with the pressure cooking instructions. This way, you’ll enjoy the same delicious, vibrant flavors with minimal effort on the day of serving!

Instant Pot Steak Fajita Bowls Recipe FAQs
How do I choose ripe peppers for my Instant Pot Steak Fajita Bowls?
Absolutely! Look for peppers that are firm, glossy, and free of dark spots or blemishes. When selecting green or red bell peppers, ensure they feel heavy for their size, indicating freshness. If the skin appears wrinkled or soft, it’s a sign that they may be past their prime.
What’s the best way to store leftover Instant Pot Steak Fajita Bowls?
Leftover bowls can be stored in an airtight container in the fridge for up to 3 days. Make sure they’re fully cooled before sealing to maintain freshness. To reheat, simply warm them on the stovetop or in the microwave until heated through, adding a splash of beef broth if needed to keep things juicy.
Can I freeze my Instant Pot Steak Fajita Bowls?
Definitely! For long-term storage, freeze the fajita mixture in freezer-safe containers for up to 2 months. To thaw, leave it in the fridge overnight. When you’re ready to eat, reheat gently in the microwave or on the stovetop until hot, adding a little broth or water if it seems dry.
What should I do if my steak comes out tough?
It’s important to slice the flank steak against the grain into thin strips before cooking. This ensures tenderness during cooking. If by chance, your steak does turn out tough, consider simmering the dish on low heat after pressure cooking to break down the fibers further, adding moisture with a splash of beef broth while it cooks.
Are there any allergies I should consider when making Instant Pot Steak Fajita Bowls?
Very! This recipe contains common allergens like beef and avocado oil. If you’re cooking for someone with allergies, you can easily swap out beef for chicken or a vegetable protein, and use a neutral oil like grapeseed or canola. Always double-check the spices for potential allergens if you’re using pre-mixed varieties.
How can I modify this recipe for a lower-carb diet?
Easily! The Instant Pot Steak Fajita Bowls can be made even lower in carbs by serving them over cauliflower rice or a bed of leafy greens instead of traditional rice or tortillas. You can also skip the tomato paste if you’re watching your carb intake closely, using extra broth for flavor instead.
