Easy Fajita Veggie Sauté
A vibrant and quick-cooking medley of bell peppers and onions, perfectly seasoned with Tex-Mex spices, ready in under 20 minutes. This versatile sauté is ideal for adding flavor and color to tacos, grain bowls, or as a healthy side.
For 4 servings
Prepare the vegetables: Thinly slice the bell peppers and onion into uniform strips. Mince the garlic cloves.
Heat the oil: Heat a large skillet or cast-iron pan over medium-high heat. Add the avocado or olive oil and let it shimmer.
Sauté the onions: Add the sliced onions to the hot skillet and cook for 3-4 minutes, stirring occasionally, until they start to soften and become translucent.
Add peppers and garlic: Stir in the sliced bell peppers and minced garlic. Continue to cook for another 3-4 minutes, stirring frequently, until the peppers begin to soften but still retain a slight crispness.
Season the vegetables: Sprinkle the fajita seasoning blend, salt, and black pepper over the vegetables. Toss well to ensure everything is evenly coated.
Finish cooking: Cook for an additional 2-3 minutes, stirring, until the vegetables reach your desired tender-crisp doneness and have a slight char.
Remove from heat and finish: Take the skillet off the heat. Squeeze the fresh juice from half a lime over the sautéed vegetables.
Serve immediately: Transfer the fajita veggies to a serving dish. Garnish with fresh chopped cilantro, if desired, and serve hot.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Uniform Slicing: Cut your bell peppers and onions into similar-sized strips to ensure they cook evenly and finish at the same time.
- 2Don't Overcrowd the Pan: If you're doubling the recipe or using a smaller skillet, cook the vegetables in two batches. Overcrowding can steam the veggies instead of searing them, resulting in a less desirable texture.
- 3High Heat for Best Texture: Maintain medium-high heat throughout the cooking process. This helps achieve a nice tender-crisp texture with a slight char, characteristic of good fajita vegetables.
- 4Customize Your Seasoning: Feel free to adjust the fajita seasoning to your preference. Add a pinch of smoked paprika for depth, a dash of cayenne for more heat, or extra cumin for earthiness.
Adapt it for your goals.
