Why You Should Try Zucchini Gratin with Yellow Squash Recipe
Ever wondered how simple veggies can transform into a dish that makes everyone ask for seconds? This gratin combines the mild sweetness of yellow squash with the slight earthiness of zucchini, all baked under a blanket of cheesy goodness. It’s comfort food without the guilt, and it’s surprisingly easy to whip up. Plus, it’s a great way to use up summer squash before they take over your kitchen.
Variations I’ve Tried
I’ve played around with this recipe more times than I can count. Sometimes I swap out the Gruyère for sharp cheddar if I’m feeling bold. Other times, I toss in some fresh thyme or rosemary for an herby twist. Adding a sprinkle of breadcrumbs on top gives it a nice crunch, but skipping them keeps it smooth and creamy—both ways work wonders. Ever tried it with a dash of nutmeg? It adds a subtle warmth that’s just right.

Serving Ideas for Zucchini Gratin with Yellow Squash
This gratin pairs beautifully with grilled chicken or fish, but it also holds its own as a vegetarian main.

Holly’s Pro Tips for Zucchini Gratin with Yellow Squash
- Slice the veggies evenly to ensure they cook uniformly.
- Don’t skip sautéing the onions and garlic; it adds a depth of flavor you’ll thank me for.
- If your squash is watery, sprinkle some salt on the slices and let them sit for 10 minutes, then pat dry. This prevents a soggy gratin.
- For extra crispiness, broil the gratin for the last 2-3 minutes, but watch it closely so it doesn’t burn.
Leftovers
Keep any leftovers in an airtight container in the fridge for up to 3 days. Reheat gently to avoid drying out the dish. If you want to get fancy, pop it under the broiler for a minute to bring back that lovely golden top.
Common Mistakes to Avoid
- Overcrowding the baking dish can lead to uneven cooking. Use a dish that fits your veggies comfortably.
- Skipping the seasoning step can make the dish bland, so don’t be shy with salt and pepper.
- Using watery squash without draining can turn the gratin into a soggy mess—patience with draining pays off.
