Ingredients You’ll Need

Here’s the lineup—nothing weird, just pure comfort magic:

2–3 medium squash (zucchini, yellow squash, or a mix) – thinly sliced. Pretend you’re auditioning for a cooking show.
1 medium onion – also sliced thin, so you don’t get giant onion surprise bites.
2 cloves garlic – because duh, garlic.
1 cup heavy cream – if you’re feeling guilty, just whisper “it’s fine” while pouring.
1 ½ cups shredded cheese – Gruyère is bougie, cheddar is reliable, mozzarella is stretchy. Your call.
½ cup breadcrumbs – for that crispy top, aka the reason gratin exists.
2 tbsp butter – for sautéing and life in general.
Salt & black pepper – season like you actually mean it.
Fresh herbs (thyme or rosemary) – optional, but they’ll make you feel like you know what you’re doing.

Step-by-Step Instructions

Preheat that oven to 375°F (190°C). Don’t be lazy here. Cold oven = sad gratin.
Sauté the onions and garlic in butter until soft and fragrant. If your kitchen smells amazing already, you’re on the right track.
Layer the squash slices in a greased baking dish. Alternate colors if you want it Instagram-worthy.
Season generously with salt, pepper, and herbs. This is your chance to avoid bland-squash-disaster.
Add a handful of cheese over each squash layer. Repeat layering like a lasagna but without the Italian grandma judging you.
Pour the cream evenly over the top. Watch it slowly seep down into the layers like liquid gold.
Top with breadcrumbs + the rest of the cheese for maximum crunchy-cheesy glory.
Bake 30–40 minutes until the top is golden brown and bubbling. If you’re not drooling by now, check your pulse.
Cool for 5 minutes before diving in. Yes, I know you’re hungry, but molten cheese is not kind to tongues.

Common Mistakes to Avoid

Skipping the preheat: Don’t. Unless you enjoy 20 minutes of wondering why nothing’s cooking.
Going stingy on seasoning: Squash without salt is basically wet cardboard. Don’t do that to yourself.
Too thick slices: You’re not building a brick wall, keep them thin.
Forgetting the crispy top: Breadcrumbs + cheese = crunchy heaven. Don’t you dare skip it.

Alternatives & Substitutions

Dairy-free? Use coconut cream and a dairy-free cheese. It won’t taste the same, but hey, your stomach will thank you.
No breadcrumbs? Crush some crackers, chips, or even stale bread. Desperate times = delicious solutions.
Switch up the cheese: Parmesan for saltiness, pepper jack for spice, or feta for a tangy twist.
Different veggies: Toss in thin-sliced potatoes, carrots, or even sweet potatoes if you’re feeling experimental.

FAQ

Can I make this ahead of time?

Yep! Assemble it earlier, refrigerate, and bake when ready. Just add 10 extra minutes since cold dishes take longer to heat.

Do I really need heavy cream?

Technically, no. But swapping with milk = less creamy, less dreamy. Do you want “meh” or “yum”?

Can I freeze leftovers?

You can, but honestly, fresh is best. The texture gets a little weird after thawing.

Can I make it vegan?

Sure! Use plant-based cream and cheese. Just promise me you’ll season it aggressively so it doesn’t taste like sadness.

What’s the best squash to use?

Zucchini and yellow squash work perfectly. Mix them for color contrast and to feel fancy.

Do I need fancy cheese like Gruyère?

Nope. Any melty cheese you love will do. If it melts and tastes good, it belongs in the gratin.

Can I skip the breadcrumbs?

You could… but then it’s just cheesy squash. The crunch makes it epic. Don’t rob yourself.
