These 30-minute sheet pan shrimp fajitas roast up juicy and smoky with peppers and onions, topped with a tangy jalapeño-lime ranch. Big flavor, no mess!
Add the ranch ingredients to a food processor. Pulse everything together until smooth. Taste for salt and pepper, add any if you like. Let this hang out in the fridge until you're ready to serve this over the shrimp fajitas.
Toss the shrimp, taco seasoning, and lime juice together and set aside.
Add the onions and peppers to the sheet pan. Add the avocado oil and taco seasoning and toss until the vegetables are coated. Let them roast in a preheated 425° oven for about 10 minutes.
Carefully remove the sheet pan from the oven and add the shrimp to the pan, spreading them out into an even layer. Sprinkle the top of the shrimp and veggie evenly with the tajin. Return the shrimp and veggies to the oven and let them roast for an additional 8-10 minutes or until the shrimp are just done.
Grab a warm tortilla of choice, pile it high with the roasted veggies and shrimp. Grab that ranch dressing and drizzle until your heart's content. Finish with a fresh squeeze of lime. Eat that. And, repeat.
