This flavorful skillet dish is my weeknight hero when time is short but cravings are big. Shrimp fajitas are a go to for their quick cook time vibrant flavor and customizable toppings. The peppers and onions soften into caramelized perfection while the shrimp soak up all that citrus and spice.

Ingredients
- Shrimp: large and deveined for best flavor retention
- Bell peppers: any color adds sweetness and crunch
- Onion: sliced thin to caramelize and balance the spice
- Olive oil: supports the sear and rounds out the flavors
- Lime juice: brings brightness and helps tenderize the shrimp
- Garlic: fresh minced for the boldest flavor punch
- Fajita seasoning: homemade or clean store bought blends are best
Step-by-Step Instructions
- Marinate the Shrimp:
- Combine shrimp with fajita seasoning lime juice olive oil and garlic. Toss thoroughly and let it sit for 10 to 15 minutes. This quick marinade infuses deep flavor without overcooking from acid.
- Sauté the Vegetables:
- Heat oil in a large skillet over medium high heat. Add sliced onions and peppers. Cook for 6 to 8 minutes stirring occasionally until softened and slightly charred for a smoky edge.
- Sear the Shrimp:
- Transfer marinated shrimp into the same hot skillet. Sear on one side until pink about 2 minutes then flip and finish cooking just until opaque. Overcooking makes them rubbery so watch closely.
- Combine and Serve:
- Add the cooked vegetables back to the pan and toss with shrimp. Heat through briefly then remove from heat. Serve hot in tortillas bowls or lettuce wraps with your favorite toppings.
