Preheat your oven to 400°F (200°C). This sets the stage for roasting those lovely ingredients to golden perfection.

In a large bowl, toss red and yellow potatoes with 1 tablespoon of kosher salt. Then, spread them out on the sheet pan, ensuring they have room to roast. These hearty veggies take longer to cook, so we want them on the pan first.

Pop the sheet pan into the oven. Roast the potatoes for about 15 minutes. This gives them a nice head start to get tender and crisp.

While the potatoes are roasting, get your onion and corn ready. Cut the onion into quarters and slice the corn into thirds. Set them aside.

After 15 minutes, remove the sheet pan. Add the onion, corn, and smoked sausage to the pan. Drizzle everything with half of the melted butter and toss to coat. Sprinkle the Old Bay seasoning, smoked paprika, crushed red pepper flakes, and the remaining salt. Stir it all together, then place the pan back in the oven for another 15 minutes.

While that’s roasting away, it’s time to address the star of our show—the shrimp! In a bowl, mix the shrimp with minced garlic, the remaining melted butter, and a sprinkle of salt. This ensures that your shrimp will absorb all those delightful flavors.

After 15 minutes of roasting the sausage, corn, and onions, take the pan out once more. Add the shrimp to the pan in an even layer. Return the pan to the oven and roast for an additional 8-10 minutes. The shrimp should turn pink and opaque when cooked, which may happen quicker than you think.

Once everything is perfectly cooked, remove the pan from the oven. Squeeze fresh lemon juice all over the flavorful mixture. Garnish with chopped parsley for a pop of color and freshness, and you’re ready to serve!
