GLP-1 medications create an interesting cooking paradox: you need high-quality, nutrient-dense meals more than ever, but on some days the fatigue, nausea, or general low energy that comes with dose adjustments makes standing at a stove for 40 minutes feel impossible.

Sheet pan dinners exist for exactly this situation. One pan, minimal prep, oven does the work. This shrimp fajita sheet pan is the most effective version of that idea: shrimp cooks in 10–12 minutes, the vegetables roast in the same window, and the whole thing is done before you've finished watching a YouTube video. The result is bright, slightly charred fajita-spiced shrimp and sweet pepper strips that taste like considerably more effort than they required.

The central theme is maximum nutritional return for minimum active cooking time. Shrimp is one of the highest-protein, lowest-calorie proteins available — 28g of protein per 100g of cooked shrimp at only 100 calories. When appetite is suppressed and you can only eat a small amount, that ratio matters enormously. Three or four shrimp with some roasted peppers and a corn tortilla is a nutritionally complete eating occasion.

Why This Works on GLP-1

Shrimp is remarkably easy to digest. Its soft texture, mild flavor, and low fat content make it consistently well-tolerated even during periods of GI sensitivity. It also cooks so quickly that there is no risk of the kitchen filling with prolonged cooking smells — which many GLP-1 users identify as a nausea trigger.

The vegetables here — bell peppers and red onion — are sweet when roasted and provide prebiotic fiber that supports gut health — particularly important for Wegovy or Mounjaro users. Roasting significantly reduces the gas-producing compounds that can make raw cruciferous vegetables uncomfortable. This is a gentler preparation than a stir-fry or raw salad.

Ingredients (serves 4)

  • 1½ lbs (680g) large raw shrimp, peeled and deveined (fresh or thawed from frozen)
  • 3 bell peppers (mix of red, yellow, and orange), sliced into strips
  • 1 large red onion, sliced into half-moons
  • 3 tablespoons olive oil
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon dried oregano
  • ¼ teaspoon salt
  • ¼ teaspoon black pepper
  • Juice of 1 lime (divided)

To serve:

  • Small corn or whole-wheat flour tortillas
  • Plain Greek yogurt or guacamole
  • Fresh cilantro
  • Lime wedges
  • Hot sauce (optional)

Instructions

  1. Preheat the oven to 220°C (425°F). Line a large rimmed baking sheet (or two sheets — don't crowd the pan) with parchment. Crowding causes steaming instead of roasting, and you want charred edges.

  2. Season the vegetables. In a large bowl, toss the bell pepper strips and onion with 2 tablespoons of olive oil, half the spice mixture (1 tsp chili powder, ½ tsp cumin, ½ tsp paprika, and the oregano), half the lime juice, salt, and pepper. Spread evenly on the prepared pan.

  3. Roast the vegetables first. Place the pan in the oven and roast for 10 minutes while you prepare the shrimp.

  4. Season the shrimp. Pat the shrimp dry with paper towels — this is the key to browning rather than steaming. In the same bowl, toss shrimp with the remaining olive oil, remaining spices (garlic powder, onion powder, remaining chili powder and cumin), and the remaining lime juice.

  5. Add shrimp to the pan. After the vegetables have had their 10 minutes, push them to one side of the pan and add the shrimp in a single layer. Return to the oven.

  6. Roast together for 8–10 minutes. The shrimp are done when they are pink and curled — they should be just cooked through, not rubbery. The vegetables should have charred edges. Keep a close eye after 8 minutes: overcooked shrimp becomes tough quickly.

  7. Serve. Warm the tortillas directly over a gas burner for 30 seconds per side, or wrap them in a damp paper towel and microwave for 30 seconds. Load the tortillas with shrimp and peppers. Top with a spoonful of Greek yogurt, cilantro, and an extra squeeze of lime.

Frequently Asked Questions

Can I use frozen shrimp instead of fresh?
Yes — and frozen is often the better choice. Raw peeled and deveined shrimp sold frozen is frequently higher quality than the "fresh" shrimp at the seafood counter, which was usually frozen and thawed before display. Thaw overnight in the fridge or in 20 minutes under cold running water. Pat completely dry before seasoning.
What if tortillas feel like too much on a difficult day?
Skip them entirely. Serve the shrimp and roasted peppers over a small scoop of cauliflower rice, or alongside plain Greek yogurt as a dipping sauce. The fajita seasoning is strong enough to stand on its own without the tortilla, and you still get the full protein and vegetable benefit.
How do I handle portion control with shrimp?
Shrimp are naturally pre-portioned, which makes them ideal for GLP-1 eating. Three shrimp and a half-cup of peppers is a legitimate small eating occasion at around 100 calories and 8g of protein. There is no cutting, no measuring, no overthinking — pick up a few pieces, eat them, and check how you feel before deciding whether to have more.
What if I'm sensitive to spicy food right now?
This recipe is intentionally mild, but you can make it even gentler. Reduce the chili powder to 1 teaspoon and skip any hot sauce at the table. The dish still has significant flavor from the smoked paprika, cumin, garlic powder, and lime — none of which cause heat-related GI irritation.
