Step‑by‑Step Instructions for Creamy Zucchini Gratin with Yellow Squash
Step 1: Preheat the Oven
Start by preheating your oven to 450°F (232°C). This ensures a hot environment for baking your Creamy Zucchini Gratin with Yellow Squash, allowing the cheese to melt beautifully and develop a lovely golden crust. While the oven warms, gather your ingredients and equipment to streamline the cooking process.
Step 2: Sauté the Onion
In an ovenproof skillet, melt 2 tablespoons of butter over medium heat. Add thinly sliced onion and sauté for about 5 minutes until the edges are browned and fragrant. Stir occasionally to prevent burning and ensure even cooking. The softened onion will serve as a flavorful base for your gratin.
Step 3: Add Garlic
Once the onions are nicely caramelized, add minced garlic to the skillet and cook for an additional minute. Stir frequently until the garlic becomes fragrant and golden, which should only take about a minute. This step deepens the flavor profile of the Creamy Zucchini Gratin, making every bite delightful.
Step 4: Stir in Cream
Pour in 1 cup of heavy cream, bringing it to a gentle simmer. Allow the mixture to bubble for 2-3 minutes, stirring occasionally, until it thickens slightly. This will help create the rich, velvety sauce that envelops the zucchini and yellow squash, building the creamy foundation of your gratin.
Step 5: Melt the Cheese
Sprinkle in 1 cup of grated Parmesan cheese, stirring until it’s fully melted and incorporated into the creamy mixture. The cheese will add a savory depth that perfectly complements the other ingredients. The sauce should be smooth and creamy by the time you finish this step, creating an inviting base for the vegetables.
Step 6: Add the Vegetables
Gently fold in the sliced zucchini and yellow squash, ensuring they’re well coated with the creamy sauce. Cook for an additional 4-5 minutes over medium heat, stirring occasionally, until the squash begins to soften but still retains some bite. This step is crucial for achieving the perfect texture for your Creamy Zucchini Gratin.
Step 7: Top with Gouda
Once the vegetables are ready, remove the skillet from heat and sprinkle 1 cup of shredded smoked gouda over the top. Make sure the cheese covers the entire surface evenly, as this will create a deliciously gooey topping during baking. Take a moment to admire the vibrant colors before it heads into the oven.
Step 8: Bake the Gratin
Place the skillet into the preheated oven and bake for 15-20 minutes. Keep an eye on it, and look for the cheese to become golden and bubbly. The gratin is done when the top is beautifully browned, creating a comforting layer over the tender zucchini and yellow squash underneath, ready to be served!

Expert Tips for the Best Zucchini Gratin

Zucchini Gratin with Yellow Squash Recipe FAQs
How do I select the right zucchini and yellow squash for the gratin?
Absolutely! Look for zucchini and yellow squash that are firm with shiny, smooth skin. Smaller varieties are the best choice as they tend to be more tender and less watery. Avoid any vegetables that have dark spots or are overly soft, as these may compromise the texture of your gratin.

To store your leftovers, make sure to place them in an airtight container in the fridge. They can last up to 3 days.

Drain off any excess liquid before folding them into the cheesy sauce, ensuring a perfect consistency!
