1-First Step: Get the oven and pan ready Start by heating your oven to 425°F. This higher temperature helps the shrimp cook fast while giving the broccoli those lightly browned edges that make sheet pan dinners so good. Line a large rimmed sheet pan with parchment paper or foil if you want easy cleanup, and lightly coat it with cooking spray if needed. While the oven heats, gather everything you need. This recipe moves quickly once the shrimp hits the pan, so having your garlic minced and broccoli cut into florets before you begin helps a lot. If you are cooking for a family, this is a great time to let kids rinse the broccoli or help measure the parmesan.

2-Second Step: Mix the garlic butter In a large bowl, combine the melted butter, minced garlic, olive oil, salt, pepper, and garlic powder. Stir well so the seasoning blends into the butter. This is the flavor base for the whole dish, so make sure the garlic is spread evenly through the mixture. If you like a stronger garlic taste, you can let the garlic sit in the warm butter for a minute or two before adding the shrimp and broccoli. That small pause gives the garlic time to release more flavor. If you want a lighter version, you can slightly reduce the butter and add a touch more olive oil.

3-Third Step: Add the shrimp and broccoli Add the shrimp and broccoli florets to the bowl with the garlic butter mixture. Toss everything until it is well coated. Every piece should have a light layer of butter and seasoning so the final dish tastes balanced from the first bite to the last. For best results, pat the shrimp dry before mixing. Dry shrimp brown better and soak up flavor more easily. If you are using frozen shrimp, make sure they are fully thawed and drained first. Wet shrimp can steam instead of roast, which changes the texture. Toss gently so the broccoli does not break apart, but make sure the shrimp is coated all over.

4-Fourth Step: Spread everything on the sheet pan Pour the shrimp and broccoli onto the prepared sheet pan and spread them into a single layer. This matters more than people think. If the pan is crowded, the ingredients steam instead of roast, and you miss out on that nice caramelized edge. Try to keep the shrimp in one layer and the broccoli pieces spaced out as much as possible. If your pan looks packed, use a second pan. That is often the best move for even cooking. A roomy pan gives you better texture and keeps the garlic butter from pooling too much in one spot.

5-Fifth Step: Roast until just cooked through Place the sheet pan in the hot oven and bake for 12 to 15 minutes. Shrimp cook fast, so start checking at the 12-minute mark. They should turn pink, opaque, and curl into a loose C shape. The broccoli should be tender-crisp with a few browned edges. If you want the shrimp a little more golden, you can switch the oven to broil for the last 1 to 2 minutes. Keep a close eye on it, because shrimp can go from perfect to overcooked very quickly. Broiling is optional, but it adds a little extra color and a lightly toasted finish to the parmesan.

6-Sixth Step: Add parmesan and lemon When the pan comes out of the oven, sprinkle the grated parmesan cheese evenly over the shrimp and broccoli. The residual heat will soften it just enough to help it cling to the food. Then squeeze fresh lemon juice over the top or serve with lemon wedges on the side. The lemon is not just a garnish. It brightens the rich butter and gives the dish that classic shrimp scampi feel. If you like extra tang, add a second squeeze right before serving. This final step is simple, but it makes the flavors pop in a big way.

7-Final Step: Serve while hot Serve this sheet pan shrimp scampi with broccoli right away while the shrimp are tender and the broccoli still has a little bite. Spoon any buttery juices from the pan over each serving for extra flavor. If you want to make it a full meal, pair it with rice, pasta, quinoa, or warm bread to soak up the sauce. This dish serves about 4 people, depending on appetite and what you serve alongside it. It is great for a weeknight family dinner, a date night meal, or a quick meal prep option when you want something simple but still satisfying.
