Some nights I want something that’s cozy and satisfying, but also light enough that I don’t immediately need a nap after dinner. That’s when I turn to this Zucchini and Shrimp Gratin with Garlic—a dish that’s hearty, packed with flavor, and surprisingly good for you. It’s got golden, melty cheese, juicy shrimp, tender zucchini, and just enough garlic to make it pop. Think comfort food, but with a Mediterranean twist.
Whether I’m serving this as a main dish or a classy side for a dinner party, it’s always a hit. And the best part? It’s easy to prep, naturally gluten-free, and feels way more indulgent than it really is.
Why This Shrimp Zucchini Gratin Works
This dish isn’t just about layering ingredients—it’s about balancing them. Here’s why I love it:
- Zucchini becomes silky and savory when roasted, soaking up all the garlicky goodness.
- Shrimp adds lean protein and cooks in minutes, making this a fast, filling meal.
- The cheese forms a golden crust that makes each bite creamy and crave-worthy.
- It’s versatile: You can serve it on its own, with crusty bread, or next to rice or pasta.
Let’s break down how I bring it all together.
Ingredients You’ll Need
(Serves 4 | Prep Time: 15 mins | Cook Time: 25–30 mins)
- 2 medium zucchinis, thinly sliced
- 1 tablespoon olive oil
- 3 cloves garlic, minced
- 1 pound large shrimp, peeled and deveined
- Salt and pepper, to taste
- 1 teaspoon dried thyme or Herbes de Provence
- ½ cup heavy cream or crème fraîche (optional, for creamier texture)
- ½ cup grated Gruyère or mozzarella cheese
- ¼ cup grated Parmesan cheese
- Fresh parsley or basil, for garnish (optional)
How I Make Zucchini and Shrimp Gratin
1. Prep the Zucchini
I preheat my oven to 375°F (190°C), then slice the zucchinis into thin rounds. I lay them out in a lightly oiled baking dish and season them with a bit of salt, pepper, and a drizzle of olive oil. These roast in the oven for about 10 minutes to soften slightly before adding the shrimp.
2. Season and Sauté the Shrimp
While the zucchini is roasting, I toss the shrimp with garlic, olive oil, and thyme (or Herbes de Provence if I want a French twist). I sauté them in a skillet for just 2–3 minutes—just enough to get a bit of color, not to fully cook them.
3. Layer and Cream (Optional)
Once the zucchini is slightly softened, I remove the baking dish and layer the shrimp evenly over the top. If I’m going for a richer version, I pour a little cream or crème fraîche over the whole thing—it melts into the layers and makes everything extra luscious.
4. Add Cheese and Bake
Next comes the best part: the cheese. I sprinkle Gruyère or mozzarella over the top, followed by the Parmesan for that nutty finish. Then it all goes back into the oven for another 15–20 minutes, until the cheese is bubbly and golden and the shrimp are perfectly cooked.
5. Garnish and Serve
I finish the dish with a handful of chopped parsley or basil for color and freshness. Served hot from the oven, it’s melty, fragrant, and totally irresistible.
My Tips for the Best Gratin Every Time
- Slice zucchini evenly so it cooks at the same rate. A mandoline helps, but a sharp knife works fine.
- Don’t overcook the shrimp in the pan—they’ll finish in the oven.
- Add breadcrumbs on top if you want extra crunch.
- Use crème fraîche for a tangy, richer variation that still feels light.
What I Serve With This Gratin
This dish is a standout on its own, but here’s how I sometimes round out the meal:
- Crusty bread to mop up the cheesy, garlicky juices
- Simple green salad with lemon vinaigrette
- A glass of dry white wine like Sauvignon Blanc or Pinot Grigio
- Rice or quinoa if I want something a little heartier on the side
