Are fajitas good for protein?

Absolutely! When made with lean proteins like chicken breast, tofu, or tempeh, high-protein sheet pan fajitas meal prep can provide 30–35 grams of protein per serving. This makes them ideal for muscle repair, satiety, and keeping energy levels steady throughout the day. Even with plant-based swaps like tempeh, these fajitas remain a strong protein source compared to many typical lunch options. Many fitness-focused home cooks use sheet pan fajitas as part of their high protein meal prep rotation because of their convenience and nutrient density.

Are fajitas ok for weight loss?

Yes! These healthy fajita recipes are naturally portion-controlled, balanced, and nutrient-dense. Lean proteins combined with fiber-rich peppers and onions help you feel full without excess calories. By swapping high-calorie toppings for lighter options, like salsa instead of sour cream or whole-grain tortillas instead of fried shells, you can enjoy flavorful fajitas while supporting a calorie-conscious meal plan. Many in the fitness and meal prep community swear by sheet pan fajitas for sustainable, weight-friendly lunches.

How many calories are in sheet pan chicken fajitas?

A typical serving of high-protein sheet pan fajitas meal prep (including chicken, peppers, onions, and one tortilla) has roughly 420 calories. Protein clocks in around 35g, carbs about 32g, and fat 14g. Swapping plant-based proteins or skipping tortillas can slightly alter the numbers, but overall, these fajitas remain a high protein, moderate-calorie meal perfect for meal prep or school lunches.

What temperature do you cook fajitas on a sheet pan?

For the best results, preheat your oven to 400°F (200°C) . Roast protein first, then add veggies halfway through to avoid sogginess and ensure everything cooks evenly. This temperature keeps chicken juicy, veggies crisp, and helps maintain the flavors of your meal prep fajitas without overcooking. Many community-tested methods recommend this roasting approach for optimal texture and flavor.
