Instructions

Step 1 Pour 2 tablespoons of olive oil into a medium pan over medium heat and wait until it starts shimmering—that’s your signal it’s ready. Add the finely chopped garlic and chilli flakes, cooking them for 2-3 minutes until the garlic turns lightly golden and your kitchen smells absolutely amazing. Pour in the passata along with a splash of water to help the sauce come together smoothly.

Step 2 Toss in the torn basil leaves and a generous pinch of salt, then bring everything to a gentle boil. Once it’s bubbling, reduce the heat to a simmer and place a lid on the pan, leaving it slightly ajar so steam can escape. Let this bubble away for 20-25 minutes while the flavors deepen and the sauce reduces to a rich, velvety texture.

Step 3 Pour the remaining 75ml of oil into a deep frying pan and warm it over medium heat until it’s hot but not smoking. Working in batches so you don’t overcrowd the pan, fry the courgette slices for 2-3 minutes on each side until they’re gorgeously golden and tender. Transfer each batch to a plate lined with kitchen paper to drain off any excess oil—this keeps them from getting greasy.

Step 4 Once your sauce has reduced and thickened beautifully, stir in the red wine vinegar and sprinkle in the sugar. Give it a taste and adjust the seasoning with more salt if needed—this is your chance to make it perfect for your palate.

Step 5 Heat your oven to 200°C (180°C fan/gas mark 6) while you assemble your masterpiece. Spoon a generous ladleful of sauce onto the bottom of a roasting dish to create your base layer. Arrange some of the fried courgettes on top, then scatter over mozzarella and a sprinkling of parmesan. Keep layering these ingredients—sauce, courgettes, cheese—until you’ve used everything up, making sure to save some of both cheeses for the glorious top layer.

Step 6 Sprinkle the pine nuts over the top if you’re using them (they add the most wonderful nutty crunch), then slide the dish into your preheated oven. Bake for 30-35 minutes until the cheese is golden, bubbling, and irresistibly melty.

Step 7 Here’s the hardest part—letting it cool for 15 minutes before diving in. Trust me on this one; those few minutes let the layers set so each serving holds together beautifully. Serve it alongside a crisp green salad, and watch everyone go back for seconds.

Substitutions

Can’t find courgettes? Yellow summer squash works perfectly in this Gluten-Free Italian Zucchini Casserole and gives you nearly identical results. You can even mix both for a prettier presentation with alternating green and yellow layers.

No passata on hand? Crushed tomatoes or even good-quality canned tomatoes blended smooth will work just fine. Just make sure whatever you choose is certified gluten-free, since some tomato products sneak in additives or thickeners.

Dairy-free version needed? Swap the mozzarella and parmesan for your favorite plant-based cheese alternatives. Look for brands that melt well—I’ve had great success with cashew-based mozzarella in this Gluten-Free Zucchini Parmesan Bake.

Fresh basil too pricey? Use 2 teaspoons of dried Italian herbs instead, adding them when you start the sauce. You’ll lose some of that fresh, bright flavor, but it’ll still taste wonderfully aromatic and comforting.

Troubleshooting

Watery finished dish? Your courgettes naturally contain lots of moisture, which releases during cooking. Try salting your sliced courgettes and letting them sit for 20 minutes before patting them dry and frying—this draws out excess water before it can dilute your beautiful sauce.

Cheese not browning? Switch your oven to the grill setting for the last 3-4 minutes of cooking, but watch it carefully. That blast of direct heat creates those gorgeous golden spots everyone fights over.

Sauce too thick? Thin it with a splash of water, vegetable stock, or even a bit of white wine. The sauce should coat the back of a spoon but still flow easily when you ladle it.

Courgettes going soggy during frying? Make sure your oil is hot enough before adding them, and don’t overcrowd the pan. Each slice needs space to fry properly rather than steam, which keeps them tender yet golden instead of limp and greasy.

Storage & Meal Prep

This Gluten-Free Courgette Parmigiana actually tastes even better the next day once all the flavors have had time to mingle. Store leftovers in an airtight container in the fridge for up to 4 days, then reheat portions in the oven at 180°C until warmed through and bubbly again.

You can prep components ahead to make weeknight dinners easier. The tomato sauce keeps beautifully in the fridge for 5 days or freezes for up to 3 months. Fry your courgettes the morning of or even the night before, then assemble and bake when you’re ready to eat.

Serving Suggestions

Well… this dish is pretty much a complete meal on its own, but I love serving it with a simple arugula salad dressed in lemon and olive oil. The peppery greens cut through the richness perfectly.

For a heartier spread, add some crusty gluten-free bread on the side for mopping up that incredible sauce. You could also pair it with my complete gluten-free comfort food collection for an Italian-inspired feast that’ll impress any crowd.

Variations

Kid-friendly version: Reduce the chilli flakes to just a pinch or leave them out entirely. Kids seem to love the mild, cheesy layers, and you can always offer hot sauce on the side for the adults.

Protein boost: Layer in some cooked Italian sausage (check it’s gluten-free) or leftover rotisserie chicken between the courgette layers. This turns it into an even more substantial main course that works beautifully for meal prep.

Mediterranean twist: Add layers of roasted red peppers and sun-dried tomatoes along with the courgettes. Swap half the mozzarella for crumbled feta, and you’ve got a Greek-Italian fusion that’s absolutely delicious.

Herb garden upgrade: Don’t stop at basil—try adding fresh oregano, thyme, or even some torn sage leaves to the sauce. Each herb brings its own personality, and using what’s growing in your garden makes this Gluten-Free Zucchini Parmigiana feel even more special.

FAQs About Gluten-Free Courgette parmigiana

Why This Recipe Works

Man, oh man, the beauty of this Gluten-Free Courgette Parmigiana is in its simplicity. By skipping the breading process entirely, you’re not just making it gluten-free—you’re actually letting the sweet, delicate flavor of the courgettes shine through. Each golden slice soaks up just enough of that garlicky tomato sauce while staying tender but not mushy.

The layering technique creates pockets of melted mozzarella that stretch dramatically when you serve it (you know, the cheese pull that makes everyone grab their phones). Meanwhile, the parmesan adds that salty, nutty depth that makes every bite completely crave-worthy.

This recipe also works brilliantly for those moments when your garden is overflowing with summer squash, or when courgettes are on sale at the market. It’s become my go-to for everything from casual Sunday dinners to bringing a dish to summer potlucks—and it always disappears fast.
