Step-by-Step Instructions

Ingredients (exact quantities)

1 1/4 lbs (20 oz / ~567 g) beef flank steak or skirt steak
3 tablespoons olive oil (for marinade)
1 tablespoon olive oil (for cooking steak)
1/3 cup fresh lime juice (juice of about 2 limes)
4 cloves garlic, minced
1 teaspoon chili powder
1/2 teaspoon ground cumin
3/4 teaspoon fine sea salt (for marinade)
1/4 teaspoon smoked paprika
1/4 cup fresh cilantro leaves, chopped (plus extra for garnish)
Sea salt to taste (for finishing)
2 tablespoons olive oil (for veggies)
3 bell peppers (assorted colors), sliced into strips
1 large onion, sliced into strips
12 oz cauliflower rice (frozen or fresh, ~340 g)
Fresh lime juice (for finishing)
Optional toppings: avocado or guacamole, dairy-free sour cream, fresh salsa, extra cilantro, sliced jalapeños

Optional ingredients & substitutions

Swap steak for sliced chicken breast or shrimp (adjust cook time).
Use coconut aminos + a dash of fish sauce for extra umami (gluten-free).
Replace cauliflower rice with riced broccoli or cabbage for variety.
Add a pinch of cayenne or chipotle for extra heat.

Preparation & cooking directions (numbered)

Marinade: In a large bowl, whisk together 3 tablespoons olive oil, 1/3 cup lime juice, minced garlic, 1 teaspoon chili powder, 1/2 teaspoon ground cumin, 3/4 teaspoon fine sea salt, 1/4 teaspoon smoked paprika, and 1/4 cup chopped cilantro. Add the steak and turn to coat thoroughly. Cover and refrigerate for at least 2 hours, ideally overnight.
Bring to room temperature: Take the steak out of the fridge about 20 minutes before cooking so it comes closer to room temp — this helps even cooking. Pat dry with paper towels and lightly sprinkle surface with sea salt.
Preheat skillet: Heat a cast-iron or heavy skillet over high heat until smoking lightly. Add 1 tablespoon olive oil and swirl to coat.
Sear the steak: Place the steak in the hot pan and sear 4 minutes per side for medium-rare. For accuracy, use a meat thermometer — aim for 125–130°F (52–54°C) for medium-rare, keeping in mind it will rise a bit while resting.
Rest & slice: Remove the steak and tent with foil. Rest for 10 minutes, then slice thinly across the grain to keep bites tender.
Sauté peppers & onions: In the same skillet, add 2 tablespoons olive oil and return over medium-high heat. Add sliced peppers and onion with a pinch of sea salt. Sauté 5–7 minutes until slightly charred but still with a bit of bite.
Cook cauliflower rice: In another pan, heat 1 tablespoon olive oil. Add cauliflower rice and cook 4–6 minutes, stirring, until warmed through and slightly golden at the edges. Season with sea salt and a squeeze of fresh lime.
Build the bowl: Start with a generous scoop of cauliflower rice, top with sliced steak and the sautéed pepper-onion mix. Finish with avocado or guacamole, dairy-free sour cream, fresh salsa, extra cilantro, and another squeeze of lime.

Practical tips

Don’t overcrowd the pan when searing the steak — work in batches or use a very large skillet. Overcrowding causes steaming instead of searing.
Always slice steak against the grain to maximize tenderness.
Resting is non-negotiable: it lets juices redistribute so slices stay juicy.
If using frozen cauliflower rice, thaw and drain excess moisture to avoid a soggy base.
Use a thermometer to hit your desired doneness rather than relying on time alone.

Best Pairings

Drinks: Sparkling water with lime, unsweetened iced tea, or a dry sparkling rosé for a festive touch (if not strictly keto).
Sides: A simple green salad with avocado-lime vinaigrette, or a small bowl of pico de gallo.
Low-carb swap: Serve with warmed low-carb tortillas or lettuce wraps for taco-style handhelds.
Garnish ideas: Pickled red onions, sliced radishes, or cojita-style cheese (if dairy is allowed).
Presentation tip: Layer colors — cauliflower rice first, steak fanned across, veggies on one side, bright avocado and cilantro on top — it makes a lively, restaurant-style bowl.

Storage Instructions

Room temperature: Do not leave cooked steak or assembled bowls at room temp for more than 2 hours (1 hour if ambient temperature is above 90°F/32°C).
Refrigerator: Store components separately in airtight containers for best texture. Marinated raw steak should be refrigerated and cooked within 24 hours if you marinated only 2 hours; otherwise cooked leftovers keep 3–4 days. Cooked steak, veggies, and cauliflower rice will keep well for up to 4 days.
Freezer: Cooked steak (sliced) and cauliflower rice freeze well for 2–3 months in airtight, freezer-safe containers. Thaw overnight in the refrigerator before reheating.
Reheating: Reheat steak gently in a skillet over medium-low with a splash of broth or oil to avoid drying; reheat cauliflower rice in a pan or microwave with a sprinkle of water and a cover to steam for 30–60 seconds.

Chef’s Advice

Best cuts & why: Flank or skirt steak are great because they soak up marinade and slice beautifully across the grain; flank offers a lean, beefy profile, while skirt brings slightly more marbling and flavor.
Doneness cues: For medium-rare, aim for 125–130°F pulled temperature; medium is 135–140°F. Remember carryover cooking during rest raises temp ~5°F.
Heat management: Use high heat for the sear to build a deep crust quickly; reduce to medium-high for vegetables to get char without burning.
Flavor layering: Marinate longer for deeper flavor but never marinate acidic mixes (like lime) more than 24 hours for texture reasons.
Texture tip for cauliflower rice: For fluffier rice, dry-pan roast it over medium-high in a single layer for a couple of minutes before stirring.

Creative Twists

Shrimp Fajita Bowl: Swap the steak for large shrimp (marinate 15–30 minutes) and sear 1–2 minutes per side until just opaque.
Vegetarian/Vegan: Replace steak with sliced, marinated portobello mushrooms or seared tofu for a plant-forward bowl; add more lime and smoked paprika for meaty umami.
Spicy Chipotle Bowl: Add 1–2 minced chipotles in adobo to the marinade and finish with a drizzle of chipotle-lime mayo (use dairy-free mayo if needed).
Mediterranean Twist: Swap fajita spices for za’atar and lemon in the marinade, serve over cauliflower rice with olives, cucumber, and dairy-free tzatziki.
Tex-Mex Casserole: Layer sliced steak, sautéed peppers and onions, cauliflower rice, and a sprinkle of keto-friendly cheese; broil briefly for a melty top.

Recipe Q&A

Q: Can I use chicken instead of steak?
A: Yes — use boneless skinless chicken breast or thigh, marinate 30–60 minutes, and pan-sear until internal temp reaches 165°F (74°C). Adjust cook times accordingly.

Q: How do I keep cauliflower rice from getting soggy?
A: Remove excess moisture (especially if frozen), cook over medium-high heat without covering, and avoid stirring constantly so it can dry and brown slightly.

Q: Is this suitable for strict keto?
A: Yes — at ~11 g net carbs per serving (without heavy toppings), this fits well within typical keto limits. Adjust toppings (avoid sugary salsas) to keep carbs low.

Q: Can I meal-prep this for the week?
A: Absolutely. Store steak slices, sautéed peppers/onions, and cauliflower rice in separate containers in the fridge and assemble bowls as needed for up to 4 days.

Q: How can I add more fat (if I need more calories for keto)?
A: Add a drizzle of olive oil, a larger portion of avocado, or a spoonful of full-fat dairy-free sour cream to increase healthy fats.
