How to Make High Protein Steak Fajita Bowl Recipe
Step 1: Prepare the Marinade and Marinate the Steak
Start by whisking together olive oil, lime juice, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper in a small bowl. This marinade is the heart of the dish, infusing the steak with bold, smoky flavor while tenderizing it. Pour half the marinade over your flank steak or sirloin and let it sit for at least 30 minutes, or up to 8 hours if you have the time. This step really makes a difference in building those delicious layers of taste.
Step 2: Cook the Steak
Heat a large skillet over medium-high heat. Place the marinated steak in the hot pan and cook for about 4 to 5 minutes on each side for a perfect medium doneness, or adjust according to your preferred level. After cooking, transfer the steak to a plate and let it rest for several minutes. Resting allows the juices to redistribute, ensuring juicy, tender slices instead of dry meat.
Step 3: Sauté the Peppers and Onions
Using the same skillet, toss in the sliced bell peppers and red onions along with the remaining marinade. Sauté for 5 to 7 minutes until the vegetables are tender-crisp and beautifully coated with those fantastic fajita spices. This step adds sweetness and a satisfying crunch, giving your bowl an awesome contrast in texture.
Step 4: Slice the Steak and Assemble the Bowl
Slice your rested steak thinly against the grain to maximize tenderness. Divide your cooked brown or cauliflower rice between four bowls, then top with the sliced steak, sautéed peppers and onions, black beans, avocado slices, and chopped fresh cilantro. Don’t forget to add lime wedges on the side for that final fresh burst of flavor. This vibrant assembly not only looks gorgeous but delivers an impressive combination of nutrients.
How to Serve High Protein Steak Fajita Bowl Recipe

Garnishes
A sprinkle of fresh cilantro is a must for that herbaceous lift. You might also add a dollop of Greek yogurt or a spoonful of salsa for extra creaminess and zing. Lime wedges are the perfect finishing touch, allowing each eater to brighten their bowl just how they like it.
Side Dishes
Serve with a simple corn tortilla or a side of tortilla chips for a little crunch and an authentic Mexican flair. A fresh salad dressed lightly with lime and olive oil can help balance the richness of the steak. If you want to keep it light, a few slices of cucumber or a quick pico de gallo work beautifully as fresh accompaniments.
Creative Ways to Present
Try layering all the components in clear glass jars for meal prep or entertaining. This presentation looks stunning and keeps everything fresh until you’re ready to dive in. You could also turn this dish into a colorful lettuce wrap by replacing the rice with crunchy butter lettuce leaves, making it a refreshing low-carb alternative perfect for warmer days.
Make Ahead and Storage
Storing Leftovers
Leftover steak fajita bowls keep wonderfully in airtight containers in the refrigerator for up to 3 days. Keep the avocado slices separate and add fresh just before serving to avoid browning. This way, your meal stays vibrant and fresh, ready whenever you need a quick high protein fix.
Freezing
While the cooked steak, peppers, onions, rice, and beans freeze well, fresh avocado does not. Freeze the main components in portioned meal prep containers and thaw overnight in the fridge for an easy reheat. Add fresh avocado and cilantro after warming for the best texture and flavor.
Reheating
Warm your bowl gently in a skillet or microwave until heated through, then add fresh garnishes and avocado right before eating. Avoid overheating to keep the steak tender and the vegetables from getting mushy. This simple reheating method lets you enjoy the flavors almost as fresh as day one.
FAQs
Can I use other cuts of steak for this recipe?
Absolutely! While flank steak and sirloin are ideal for their flavor and tenderness, you can also use skirt steak or even ribeye if you prefer a richer cut. Just adjust cooking time accordingly to avoid overcooking.
Is cauliflower rice a good substitute for brown rice?
Yes, cauliflower rice is a fantastic low-carb and lower-calorie alternative that pairs well with the bold flavors of this bowl. It cooks quickly and adds a nice, mild vegetable flavor to complement the steak and veggies.
Can I make this recipe vegan or vegetarian?
Definitely! Swap out the steak for grilled tofu or tempeh and use vegetable broth to cook the rice if needed. The spices and vegetables remain the highlights, so this dish is versatile and delicious no matter your diet.
How far in advance can I marinate the steak?
You can marinate the steak anywhere from 30 minutes up to 8 hours. The longer it marinates, the more intense the flavor and tenderness you’ll get. Just make sure to keep it refrigerated while marinating.
What can I add to increase the protein even more?
If you want to boost the protein beyond the already impressive 38 grams per serving, add a scoop of black beans or sprinkle some shredded cheese or pumpkin seeds on top. Greek yogurt as a sauce substitute can also add protein and creaminess.
