Sheet Pan Old Bay Shrimp Boil with Corn and Red Potatoes

Each serving of this Chesapeake-style sheet pan shrimp boil delivers roughly 40 grams of protein and only 385 calories, making it one of the most efficient protein-to-calorie ratios you can get from a single pan. The shrimp provides lean, fast-digesting protein alongside roasted corn and baby red potatoes that add enough complex carbohydrates to sustain afternoon energy without weighing you down. A tablespoon of olive oil keeps the fat content to around 9 grams per serving, and 6 grams of fiber from the vegetables round out the macros.

Old Bay seasoning does most of the heavy lifting here — its blend of celery salt, mustard, red pepper, and paprika coats everything on the pan with the warm, savory depth that makes a traditional shrimp boil so addictive. The roasted corn kernels caramelize and turn slightly sweet against the savory shrimp, while the red potatoes develop crisp golden edges that contrast with their creamy centers. A squeeze of fresh lemon right out of the oven ties the whole sheet pan together with bright acidity.

This is a natural fit for a GLP-1 lunch because the portion looks and feels generous — a full spread of shrimp, potatoes, and corn across the plate — without the caloric load of a fried seafood basket or butter-drenched boil. The lean protein digests smoothly without the heaviness that rich seafood preparations can bring, and the staggered roasting method keeps every component properly cooked rather than mushy.

Why This Works on GLP-1

Shrimp is one of the leanest animal proteins available, delivering about 20 grams of protein per 100 grams with almost no fat. At 40 grams of protein per serving, this sheet pan covers roughly 50–60% of most GLP-1 users' daily protein needs in a single meal. That matters because medications like Wegovy and Mounjaro reduce appetite significantly, and many users struggle to hit adequate protein targets when eating smaller volumes. Concentrating protein into satisfying, well-seasoned dishes ensures you protect lean muscle mass even as the scale moves.

The fiber content here comes from whole food sources — corn, potato skins, zucchini, and bell pepper — rather than added supplements or ultra-high-fiber ingredients that can cause bloating. For GLP-1 users dealing with the slower gastric emptying these medications produce, moderate fiber from cooked vegetables is far more comfortable than raw salads or fiber-heavy grain bowls.

Shrimp is also one of the richest dietary sources of the antioxidant astaxanthin and provides meaningful amounts of selenium and iodine, both of which support thyroid function. The relatively low fat content — about 9 grams per serving, mostly from olive oil — means this meal moves through the digestive system efficiently, reducing the nausea risk that fatty foods can trigger during the first months on GLP-1 therapy.

Ingredients (serves 2)

For the sheet pan:

• 12 oz (340g) large shrimp, peeled and deveined (tails on or off)
• 8 oz (225g) baby red potatoes, halved
• 1 ear fresh corn, husked and cut into 4 rounds
• 1 medium zucchini (200g), cut into 1/2-inch half-moons
• 1 red bell pepper (150g), cut into 1-inch chunks
• 1 tablespoon (15ml) olive oil
• 1 1/2 teaspoons Old Bay seasoning, divided
• 1/4 teaspoon garlic powder
• 1/4 teaspoon freshly ground black pepper

For serving:

• 1 lemon, cut into wedges
• 2 tablespoons fresh flat-leaf parsley, roughly chopped
• Pinch of flaky sea salt (optional)

Instructions

Prep the vegetables and preheat:

1. Preheat your oven to 425°F (220°C) and line a large rimmed sheet pan with parchment paper. This temperature is high enough to caramelize the vegetables and develop color on the shrimp without drying them out.

2. Halve the baby red potatoes and cut the corn into 4 thick rounds. Cut the zucchini into half-moon slices about 1/2-inch thick — thin enough to cook through in the time allotted but thick enough to hold their shape. Cut the bell pepper into 1-inch chunks.

Roast the vegetables in stages:

3. Toss the potatoes and corn rounds with 2 teaspoons of the olive oil, 1 teaspoon of Old Bay, the garlic powder, and the black pepper. Spread them in a single layer on the sheet pan, cut side down for the potatoes. Roast for 12 minutes — the potatoes need a head start because they take longer than everything else.

4. Remove the pan and scatter the zucchini and bell pepper around the potatoes and corn. Drizzle the remaining 1 teaspoon of olive oil over the added vegetables and toss them briefly on the pan to coat. Return to the oven for 8 minutes.

Add the shrimp and finish:

5. While the vegetables roast, pat the shrimp dry with paper towels and toss them in a bowl with the remaining 1/2 teaspoon of Old Bay. Dry shrimp is essential — any surface moisture steams instead of roasting and prevents the slight char you want.

6. Remove the pan again and nestle the shrimp in a single layer among the vegetables. Return to the oven for 5 to 6 minutes, until the shrimp are pink and just opaque through the center. They curl into a loose C shape when done — if they curl into a tight O, they are overcooked.

7. Squeeze lemon juice over the entire pan, scatter the chopped parsley on top, and finish with a pinch of flaky salt if desired. Serve directly from the sheet pan or plate alongside any remaining lemon wedges.

Practical Notes

Shrimp timing is everything. The shrimp only need 5 to 6 minutes in a 425°F oven. Set a timer — overcooked shrimp turn rubbery and chewy, which is especially unpleasant for GLP-1 users whose reduced appetite makes texture issues harder to tolerate. Pull them when they are just pink and slightly translucent at the very center; carryover heat finishes the job.

Frozen shrimp work perfectly. Thaw them in a colander under cold running water for 5 minutes before patting dry. Frozen-and-thawed shrimp are often fresher than the "fresh" shrimp at the fish counter, which were typically frozen and thawed at the store anyway. Buy peeled and deveined to save prep time.

Store and reheat for next-day lunch. Refrigerate leftovers in an airtight container for up to 2 days. Reheat gently at 300°F (150°C) for 8 to 10 minutes — the low temperature prevents the shrimp from toughening. Alternatively, eat the leftovers cold over a bed of mixed greens with an extra squeeze of lemon for a protein-packed salad.

Swap the corn for asparagus in winter. When fresh corn is out of season, substitute 6 ounces (170g) of asparagus spears trimmed and cut into 2-inch pieces. Add them with the zucchini and pepper in step 4. The calorie and fiber count stays nearly identical, and the asparagus picks up Old Bay seasoning beautifully.

For very small appetites, split into three portions. If you are in the early weeks of Mounjaro or Zepbound titration, divide this recipe into 3 servings instead of 2. You will still get about 27 grams of protein per portion at roughly 255 calories, which is a solid lunch for days when you simply cannot eat a full plate.
