Sheet pan shrimp fajitas make busy nights a breeze by transforming simple shrimp and vibrant peppers into a sizzling dinner all on one pan. Minimal prep and easy cleanup make this flavorful dish a go to whenever time is tight and taste buds crave something festive.
I still remember whipping this up for a last minute dinner with friends it was a hit that kept everyone gathered around the kitchen island assembling fajitas long after the oven timer chimed.
Ingredients
- Shrimp: fresh or frozen works just make sure they are peeled and deveined for ultimate convenience I like buying wild caught for a cleaner briny flavor
- Bell peppers: any color adds sweetness and crunch pick ones with glossy skins and firm flesh for best results
- Onion: yellow or red both bring savory sweetness slice evenly for even roasting
- Olive oil: coats everything for crisp edges and prevents sticking always reach for extra virgin if you can
- Fajita seasoning: a blend of chili cumin garlic and paprika gives signature warmth buy a good brand or make your own to control salt and spice
- Salt and pepper: round out the flavors use sea salt and freshly cracked pepper for that final depth
- Tortillas: flour or corn based on your preference go for soft and pliable ones that can hold all the filling
Instructions
- Prep the Oven:
- Preheat your oven to four hundred twenty five degrees Fahrenheit or two hundred twenty degrees Celsius so it is fully hot by the time everything hits the pan for even roasting
- Mix the Shrimp and Veggies:
- In a large bowl combine shrimp sliced bell peppers and onions drizzle with olive oil sprinkle with fajita seasoning salt and pepper Use clean hands or tongs to toss thoroughly ensuring every piece is glossy and spice coated
- Arrange on the Sheet Pan:
- Spread the shrimp and veggies in a single layer on a large rimmed baking sheet Try to keep everything spaced out so the heat circulates and you get beautifully roasted not steamed results
- Roast to Perfection:
- Transfer to your preheated oven and roast for ten to twelve minutes Keep an eye on the shrimp which should turn pink and opaque and the vegetables tender with charred edges Give the pan a shake at the halfway mark for even cooking
- Serve Warm:
- Pile the sizzling shrimp and veggies straight from the sheet pan onto warm tortillas Add your favorite toppings like a squeeze of lime or fresh cilantro if you like

I am a huge bell pepper fan and love how their natural sweetness intensifies in the oven My family jokes that any meal with extra peppers brings a little more sunshine to the table
Storage Tips
Cool any extras completely before storing Transfer leftovers to an airtight container and use within two days I like eating them cold straight from the fridge or quickly reheating in a hot skillet which revives the veggie texture better than the microwave
Ingredient Substitutions
Try using chicken tenders or strips of firm white fish in place of shrimp if you are not a seafood fan Add extra mushrooms or zucchini for a plant based option If you are out of fajita seasoning use a mix of chili powder cumin and a pinch of smoked paprika for similar warmth
Serving Suggestions
These shrimp fajitas are perfect with warm corn or flour tortillas but sometimes I set everything out taco bar style with bowls of guacamole shredded lettuce salsa and pickled onions Let everyone build their own There is never a crumb left when I do this for a game night
Cultural and Historical Context
Fajitas originated with ranch workers in Southwest Texas using cast off steak cuts and have since become a Tex Mex favorite Shrimp brings a lighter seaside twist that is common along coastal regions of Mexico and the Gulf of Mexico Cooking everything on a sheet pan suits today’s craving for both ease and bold flavors
Seasonal Adaptations
Swap in asparagus or snap peas when peppers are not in season Roast sweet potato cubes alongside the veggies for a fall spin Serve with grilled corn on the cob in the summer to make it a true seasonal feast
Success Stories
Every time I make these for a quick weeknight meal my family ends up raving about them more than fancy restaurant dinners Friends have asked for the recipe on the spot and a neighbor once texted for the secret after catching the aroma through an open window
Freezer Meal Conversion
To make ahead freeze the shrimp and veggies with spices and oil in a zip top bag Thaw overnight then roast as usual for a fuss free meal that tastes freshly cooked every time
