Ingredients

  

• 1 to 1.25 lb flank steak (or skirt steak, sirloin, or flat iron)
• 2 bell peppers (any colors), thinly sliced
• 1 medium red onion, thinly sliced
• 2 cups cauliflower rice (fresh or frozen), or mixed salad greens
• 2 tablespoons olive oil, divided
• Juice of 1 lime, plus extra wedges for serving
• 2 cloves garlic, minced
• Fresh cilantro, chopped (about 1/4 cup)
• Optional toppings: sliced avocado, Greek yogurt (or sour cream), salsa, pickled jalapeños, shredded cheese
• 1.5 teaspoons chili powder
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1/2 teaspoon oregano
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 to 1/2 teaspoon red pepper flakes (optional)
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper

Instructions

 

• Slice the steak. Trim any silver skin. Slice thinly across the grain into 1/2-inch strips for tenderness, or leave whole to sear and slice after resting. Pat dry.
• Season the meat. In a bowl, combine steak with half the olive oil, minced garlic, half the lime juice, and all the fajita seasoning. Toss to coat. Let sit 10–20 minutes at room temp while you prep veggies.
• Prep the veggies. Slice peppers and onion into thin strips. Chop cilantro. Set aside.
• Cook the cauliflower rice (or prep greens). For cauliflower rice, heat a nonstick skillet with a splash of olive oil. Sauté 4–5 minutes with a pinch of salt until just tender. Squeeze in a little lime, then set aside. If using greens, toss with a bit of lime juice, olive oil, and salt.
• Sear the steak. Heat a large cast-iron or stainless skillet over medium-high until hot. Add steak in a single layer (work in batches). Sear 2–3 minutes per side for strips, or 3–4 minutes per side for a whole piece, until nicely browned and cooked to your liking. Remove to rest on a plate. Do not overcrowd.
• Sauté peppers and onions. In the same skillet, add a drizzle of oil if needed. Toss in peppers and onions with a pinch of salt. Cook 4–6 minutes, stirring occasionally, until crisp-tender with some char. Add remaining lime juice to brighten.
• Slice (if whole) and combine. If you seared the steak whole, slice it thinly across the grain. Return steak to the pan and toss with peppers and onions for 30 seconds to warm through. Stir in chopped cilantro.
• Assemble bowls. Add cauliflower rice or greens to each bowl. Top with the steak-pepper mix. Finish with avocado slices, a spoon of Greek yogurt, salsa, or jalapeños if you like.
• Taste and adjust. Add a pinch more salt, an extra squeeze of lime, or a dash of hot sauce until it sings.

Storage Instructions

• Refrigerate: Store steak and veggies together in an airtight container for up to 4 days.Keep cauliflower rice or greens and toppings separate for best texture.
• Reheat: Warm steak and veggies in a hot skillet 2–3 minutes, or microwave briefly until heated through. Avoid overcooking to keep the steak tender.
• Freeze: You can freeze cooked steak and peppers for up to 2 months. Thaw overnight in the fridge, then reheat quickly in a skillet.Skip freezing avocado and yogurt.

Health Benefits

• Protein for strength: Lean steak is rich in complete protein and iron, supporting muscle repair and steady energy—great for workouts and busy days.
• Low-carb, nutrient-dense base: Cauliflower rice or greens deliver fiber, vitamins C and K, and volume without many carbs.
• Healthy fats that satisfy:</-strong> Olive oil and avocado add monounsaturated fats for heart health and long-lasting fullness.
• Antioxidants from colorful veggies: Bell peppers and onions bring vitamin C and phytonutrients that support immune and skin health.
• Customizable for goals:</-strong> Add Greek yogurt for extra protein, or keep toppings light for calorie-conscious meals.

What Not to Do

• Don’t overcrowd the pan. You’ll steam the meat instead of searing it, and the flavor will suffer.
• Don’t skip the rest time.</-strong> Let steak rest a few minutes before slicing so the juices stay put.
• Don’t overcook the veggies. Aim for crisp-tender with a bit of char. Mushy peppers lose their bite and brightness.
• Don’t drown it in sugary sauces. Keep it low-carb by choosing salsa, lime, and spices over sweet marinades.
• Don’t slice with the grain. Always cut across the grain for a tender chew.

Alternatives

• Protein swaps: Use chicken thighs, turkey, shrimp, tofu, or tempeh. Adjust cooking times: shrimp cooks in 2–3 minutes total; tofu benefits from pressing and a cornstarch dusting for crisp edges.
• Base options: Try shredded cabbage, zucchini ribbons, riced broccoli, or a blend of cauliflower rice and quinoa if you want a moderate-carb version.
• Dairy-free: Use coconut yogurt or skip creamy toppings.Lean on avocado and salsa for richness.
• Extra veg: Add mushrooms, cherry tomatoes, or spinach at the end for more volume and nutrients.
• Spice level: Increase red pepper flakes, add chipotle powder, or finish with hot sauce for heat.

FAQ

What Cut of Steak Works Best?

Flank, skirt, sirloin, or flat iron all work well. Flank and skirt bring bold flavor and benefit from a quick, hot sear and thin slicing across the grain. Sirloin and flat iron are naturally tender and forgiving if you prefer a bit more thickness.

How Do I Keep the Steak Tender?

Start with a hot pan, don’t overcook, and slice against the grain.

A brief rest (3–5 minutes) before slicing keeps it juicy. A splash of lime and olive oil at the end also helps with moisture and flavor.

Is This Meal Prep Friendly?

Yes. Cook steak and peppers, portion into containers, and store the base and toppings separately.

Reheat the steak and veggies quickly, then add fresh toppings to keep everything bright and crisp.

Can I Make It Truly Keto?

Absolutely. Use cauliflower rice or greens, choose full-fat Greek yogurt or cheese for toppings, and avoid sweetened sauces. Stick to avocado, salsa, and lime for clean flavor.

What If I Don’t Have All the Spices?

A store-bought fajita or taco seasoning works in a pinch.

Just watch the salt content and skip extra salt until you taste. Paprika, cumin, and chili powder are the key flavors.

Can I Cook This on a Grill?

Yes. Grill the steak over high heat to your preferred doneness, and grill peppers and onions in a grill basket until charred and tender.

Slice steak after resting and assemble as usual.

How Much Protein Is in a Serving?

Using 1.25 lb of flank steak divided into four bowls, you’ll get roughly 30–35 grams of protein per serving, plus more if you add Greek yogurt or cheese. Exact numbers vary by cut and portion size.

What’s the Best Way to Add Carbs Without Overdoing It?

Try a half-and-half base: mix cauliflower rice with a small portion of brown rice or quinoa. You’ll get extra fiber and sustained energy without spiking carbs too high.

Can I Make It Without Onions or Peppers?

Yes.

Swap in zucchini, mushrooms, or green beans for similar texture and volume. Keep the same seasoning and cooking approach for great results.

How Do I Make It Spicier Without Changing the Flavor?

Add a pinch of cayenne or chipotle powder to the seasoning, or finish with jalapeño slices or a dash of hot sauce. It lifts the heat while keeping the core fajita profile intact.

In Conclusion

This High Protein Steak Fajita Bowl delivers serious flavor, steady energy, and weeknight simplicity.
