Why this recipe works
Roasting the vegetables first gives them time to soften and caramelize before the shrimp are added, preventing the shrimp from becoming overcooked. Adding the shrimp later ensures they remain tender and juicy. The simple homemade fajita seasoning is made from individual spices rather than a premixed blend, avoiding the fillers and preservatives often added to packaged versions. This keeps the flavor clean and well-balanced. Everything cooks on one sheet pan, making it efficient without sacrificing texture.
Notes on Ingredients
Raw peeled shrimp
If using frozen shrimp, make sure they are fully thawed before cooking. Drain well and pat dry with paper towels to remove excess moisture, which helps them roast rather than steam.
Bell Peppers and Onion
You can use any combination of bell pepper colors you prefer. A red onion can be substituted for white onion if desired — both work well in this recipe.
Seasoning
I prefer to mix my own fajita seasoning so I know exactly what’s in it. Unlike many store-bought blends, this version contains only individual spices without added starches or anti-caking agents. You can use a packaged blend if you prefer, but making your own gives you better control over the flavor.
Recipe FAQ’s and tips
What kind of shrimp works best for this recipe?
Medium or large raw shrimp, peeled and deveined, work best. Fresh or frozen shrimp can be used — just make sure frozen shrimp are fully thawed and patted dry before cooking.
how long can I store this for?
Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently to avoid overcooking the shrimp.
What can I serve with Shrimp Fajitas?
Serve these shrimp fajitas with warm corn tortillas or gluten-free tortillas, guacamole, fresh lime wedges, and chopped cilantro. The acidity from the lime balances the spices and adds a little ‘zing’ to the chicken, while the guacamole adds creaminess.

Recipe Notes
Shrimp – This recipe was tested with medium shrimp, but large shrimp can be used. Increase the cooking time by 1–2 minutes as needed, just until opaque and cooked through.
Tortillas – Corn tortillas are traditional, but almond flour tortillas (such as Siete) are a good gluten-free alternative. They’re often found in the freezer or refrigerated section of larger grocery stores.
