1-First step: mix the marinade Grab a large glass or plastic bowl. Add the extra-virgin olive oil, minced garlic, dried oregano, dried basil, Kosher salt, black pepper, and lemon zest. Stir everything together until the oil looks evenly seasoned and smells amazing. This is the flavor base for your oven roasted garlic parmesan shrimp recipe, so take a second and make sure the garlic is spread through the mixture instead of clumping in one spot. If you are cooking for a family with different tastes, this is the point where you can set aside a small portion before adding extra heat later. That way, everyone gets a version they like.

2-Second step: coat the shrimp Add the peeled and deveined shrimp to the bowl and toss until every piece is coated. Use a spoon or clean hands to move the shrimp around so the seasoning reaches all sides. This step matters because it helps the shrimp roast with even flavor instead of tasting salty in one bite and plain in the next. If you are using frozen shrimp, make sure they are fully thawed and patted dry first. Wet shrimp can water down the marinade and make the final dish less flavorful.

3-Third step: marinate in the fridge Cover the bowl and refrigerate for 1 to 3 hours. This is where the shrimp soaks up all that garlicky, herby goodness. Do not rush this step if you can help it, because the short marinating time gives you a more flavorful result without making the shrimp mushy. A quick marinate is your friend here. Shrimp are delicate, so a little time in the fridge goes a long way. Try not to go past 3 hours. The lemon zest adds freshness, but too much time can change the texture of the shrimp and make it less pleasant.

4-Fourth step: preheat the oven When you are ready to cook, preheat the oven to 400 degrees Fahrenheit. This hotter oven helps the shrimp roast quickly, which keeps them juicy while also giving the Parmesan a nice finish. If you are making a second tray for a larger group, line up both pans before the oven is hot so you can move fast.

5-Fifth step: add the Parmesan Stir the grated Parmesan into the marinated shrimp mixture. Mix gently so the cheese sticks to the shrimp without clumping too much in the bowl. The cheese will melt in the oven and create that savory, lightly golden coating that makes this parmesan shrimp so satisfying. This is also a good place to add a little more black pepper if your crew likes bolder flavor. Just keep the base balanced so the garlic and lemon still shine through.

6-Sixth step: arrange for roasting Transfer the shrimp mixture to a 13×9-inch dish or a large baking sheet. Spread the shrimp out in a single layer as much as possible. That helps them roast instead of steam, which is a big deal if you want nice texture and not a watery pan situation. If you are using a baking sheet, a little parchment paper can make cleanup easier. Busy parents and students especially tend to love anything that cuts down on scrubbing later.

7-Seventh step: roast until just cooked Roast the shrimp for about 8 minutes, or until they are pink, firm, and fully cooked. Shrimp cook fast, so keep an eye on them. The moment they turn opaque and curl into a gentle C shape, they are usually done. Do not overbake them. Overcooked shrimp turn rubbery fast, and nobody wants to chew through dinner like it is a gym challenge.

8-Final step: finish and serve Once the shrimp come out of the oven, drizzle a little more olive oil over the top and sprinkle on the chopped flat Italian parsley. That fresh green finish makes the whole dish look brighter and gives the flavor a little lift. Serve immediately while the shrimp are hot and juicy. This baked garlic parmesan roasted shrimp is great with rice, pasta, roasted vegetables, or a crisp salad. It also makes a lovely appetizer for party hosts who want something easy but crowd pleasing.
