Ingredient Notes
Ground beef: An 80/20 or 85/15 ground beef blend gives the fajitas plenty of flavour while keeping the meat juicy.
Bell peppers: Using red and green peppers adds colour, sweetness, and a slight crunch.
Onion: Yellow onion works especially well because it becomes sweet and tender as it cooks.
Spices: Chilli powder, cumin, smoked paprika, oregano, onion powder, salt, and black pepper create a balanced fajita seasoning.
Lime juice: Fresh lime juice adds brightness and balances the rich beef and spices.
How to Make Ground Beef Fajitas
Cook the Ground Beef
Heat a large skillet over medium-high heat and add the olive oil. Add the ground beef and break it apart with a wooden spoon.
Cook for about 5–7 minutes, stirring occasionally, until the beef is browned and cooked through.
If there is a large amount of excess fat in the skillet, carefully drain some before continuing.
Add the Peppers and Onion
Add the sliced onion, red bell pepper, and green bell pepper to the skillet with the beef.
Cook for approximately 5–6 minutes, stirring regularly, until the vegetables become tender but still have a little texture.
Add the Garlic and Seasonings
Stir in the minced garlic, chilli powder, smoked paprika, cumin, oregano, salt, black pepper, and onion powder.
Cook for another 1–2 minutes, stirring continuously so the garlic and spices become fragrant without burning.
Finish With Lime Juice
Remove the skillet from the heat and stir in the fresh lime juice.
Taste and adjust the seasoning if needed. The finished filling should be savoury, smoky, slightly spicy, and bright from the lime.
Warm the Tortillas
Warm the tortillas in a dry skillet for approximately 20–30 seconds per side, or wrap them in foil and warm them in the oven.
Keep them covered with a clean kitchen towel so they stay soft while you prepare the fajitas.
Assemble the Fajitas
Spoon the warm ground beef and vegetable mixture into the tortillas.
Top with fresh cilantro, avocado, salsa, shredded lettuce, jalapeños, and a little sour cream if desired.
Serve immediately with lime wedges on the side.
Tips for Making the Best Ground Beef Fajitas
Use a large skillet so the beef and vegetables have enough room to cook evenly.
Do not overcook the peppers. They should be tender while still keeping some texture.
Fresh lime juice makes a noticeable difference, so use fresh lime when possible.
Warm the tortillas immediately before serving so they remain soft and flexible.
For deeper flavour, let the cooked beef and vegetables sit in the skillet for an extra minute after seasoning before adding the lime juice.
Best Ground Beef Ratio
An 80/20 ground beef blend is a great option because the extra fat helps keep the beef moist and flavourful.
If you prefer a leaner meal, 90/10 ground beef also works well. Just be careful not to overcook it, as lean ground beef can become dry more quickly.
Variations and Substitutions
Make It Spicier
Add sliced jalapeños, cayenne pepper, or your favourite hot sauce.
Add More Vegetables
You can add sliced mushrooms, zucchini, or extra bell peppers for more vegetables.
Make It Cheesy
Add shredded cheddar or Monterey Jack cheese just before serving.
Try Different Tortillas
Flour tortillas work beautifully, but corn tortillas can also be used for a different texture and flavour.
Make a Fajita Bowl
Skip the tortillas and serve the seasoned beef and vegetables over cooked rice with avocado, salsa, lime, and fresh cilantro.
What to Serve With Ground Beef Fajitas
These fajitas pair well with:
- Mexican-style rice
- Refried beans
- Black beans
- Corn salad
- Guacamole
- Fresh tomato salsa
- Avocado salad
- Tortilla chips
- Cilantro-lime rice
Storage and Reheating
Store leftover beef and vegetable filling in an airtight container in the refrigerator for up to 3–4 days.
Keep tortillas and fresh toppings separate so they remain fresh.
To reheat, place the filling in a skillet over medium heat and cook until warmed through. You can also reheat it in the microwave in short intervals, stirring between each one.
For best texture, warm fresh tortillas just before serving.
Serving Suggestion
Serve the fajitas family-style with the warm beef mixture in a large bowl and the tortillas and toppings arranged separately.
This lets everyone build their own fajitas with the toppings they enjoy most.
