📝 Ingredients:

  • 1 zucchini, sliced thin
  • 1 yellow squash, sliced thin
  • ½ cup shredded cheddar cheese
  • ¼ cup grated Parmesan cheese
  • ¼ cup heavy cream
  • 1 garlic clove, minced
  • 1 tbsp butter
  • Salt and pepper to taste

👨‍🍳 Instructions:

  1. Preheat Oven:
    Preheat your oven to 400°F (200°C). Lightly grease a small baking dish.
  2. Prepare Veggies:
    Thinly slice zucchini and yellow squash using a mandoline or sharp knife for even cooking.
  3. Make Garlic Cream Sauce:
    In a small saucepan, melt butter over medium heat. Add minced garlic and sauté for about 30 seconds until fragrant. Stir in the heavy cream and let it warm for 1 minute. Remove from heat.
  4. Assemble:
    Layer zucchini and squash slices in the dish, alternating for a pretty pattern. Season with salt and pepper.
  5. Add Cheese & Cream:
    Pour the garlic cream evenly over the veggies. Sprinkle cheddar cheese on top, then finish with grated Parmesan.
  6. Bake:
    Bake for 15–20 minutes, or until the top is golden and bubbly and the squash is tender.
  7. Serve:
    Let it rest for 5 minutes before serving. Garnish with fresh herbs if desired (thyme or parsley work great).
