🥘Keto Sheet Pan Steak Fajitas Ingredients
These are the ingredients necessary to make Keto Sheet Pan Steak Fajitas.
- Skirt Steak - If you can't find skirt steak you can use flank steak, just be aware that the cooking time may change.
- Seasonings - We love the mix of seasonings in this recipe much better than store-bought fajita mixes!
- Bell Peppers and Onion - Grab whatever color bell pepper you prefer and yellow, white, or purple onion.
A detailed list with measurements and instructions can be found on the printable recipe card at the bottom of the page.
Helpful Hint: 💡: Marinating is the name of the game! For that mouthwatering flavor infusion, let your steak, peppers, and onions marinate for at least an hour (or even better, overnight) in the zesty mix of spices, oil, and lime juice. The longer they mingle, the more fantastic the flavors become, taking your Sheet Pan Steak Fajitas to a whole new level of deliciousness!
- Skirt Steak - instead of skirt steak you could use flank steak, just know that the cooking time may change so make sure to check the internal temperature of the steak.
- Keto Tortillas - use these homemade keto tortillas or your favorite keto/low-carb tortillas.
- Vegetables - I like to use a mix of red and orange bell peppers but feel free to use whatever color you prefer. We also enjoy yellow onion but you can use white onion for a sharper bite or red onion for a more mild flavor.
- Chicken Fajitas: Swap out the steak for boneless, skinless chicken thighs or breasts. Adjust the cooking time to ensure the chicken is cooked through (165°F or 74°C).
- Shrimp Fajitas: Use large shrimp, peeled and deveined. Marinate them briefly (30 minutes) as shrimp can quickly absorb flavors. Add the shrimp to the sheet pan for the last 5 to 7 minutes of cooking.
- Vegetarian Fajitas: Skip the meat altogether and load up on colorful bell peppers, onions, and mushrooms. You can also add zucchini, cherry tomatoes, or any of your favorite veggies.
This is the equipment you will need to make Keto Sheet Pan Steak Fajitas.
Refrigeration: If you have leftover fajitas, allow them to cool to room temperature. Then, place them in an airtight container or wrap them tightly with plastic wrap. Store in the refrigerator for up to 3-4 days.
Freezing: While fajitas can be frozen, it's essential to do so before cooking the steak and vegetables. Marinate the meat and vegetables and freeze them in a single layer on a baking sheet. Once they're frozen, transfer them to an airtight container or freezer-safe bag. When you're ready to enjoy, thaw them in the refrigerator and follow the original cooking instructions.
Reheating: To reheat refrigerated fajitas, you can use the oven or stovetop. Here's how:
- Oven: Preheat your oven to 350°F (175°C). Place the fajitas on a baking sheet and cover it with aluminum foil to prevent them from drying out. Heat for about 15-20 minutes or until they are heated through.
- Stovetop: Reheat in a pan over medium heat. Add a little oil to the pan to prevent sticking. Stir occasionally until the fajitas are hot.
Remember, for the best results, consider reheating the steak and vegetables separately from any toppings, such as sour cream or fresh herbs. This way, you can ensure everything comes out at the right temperature and texture. Enjoy your leftover Sheet Pan Steak Fajitas!
When roasting your fajita mixture in the oven, keep an eye on the temperature with an instant-read thermometer. The magic number is 125 degrees for perfectly cooked steak. Achieve that ideal tenderness, and you'll be serving up a fiesta on a sheet pan every time!
FAQ about Keto Sheet Pan Steak Fajitas
Absolutely! While the recipe calls for skirt steak, you can experiment with other cuts like flank steak, flat-iron, or sirloin. Adjust the cooking time as needed for your chosen cut.
If you're short on time, you can marinate the steak, peppers, and onions for at least 15-30 minutes. While longer marinating imparts more flavor, even a short marination will enhance the taste of your fajitas.
Of course! If you prefer spicier fajitas, consider adding sliced jalapeños to the marinade or extra chili flakes. Conversely, reduce the spices if you prefer a milder flavor.
