Ingredients
- 2 tablespoons butter
- ½ onion, thinly sliced
- 1 small zucchini, sliced into rounds (1/8 to 1/4 inch thick)
- 1 small yellow squash, sliced into rounds (1/8 to 1/4 inch thick)
- 2 large cloves garlic, minced
- ½ cup heavy cream
- ¼ cup grated Parmesan cheese
- 1 cup shredded smoked Gouda cheese
Instructions
1️⃣ Preheat the oven to 450°F (230°C).
2️⃣ Sauté onions and garlic: In an oven-proof skillet, melt the butter over medium heat. Add the sliced onion and cook until the edges start to brown, about 5 minutes. Add the minced garlic and cook for another minute.
3️⃣ Prepare the cream sauce: Pour in the heavy cream and let it simmer until it’s bubbly and slightly thickened. Stir in the grated Parmesan cheese until fully combined.
4️⃣ Cook the vegetables: Add the sliced zucchini and yellow squash to the skillet. Cook for 4-5 minutes, stirring occasionally, until the vegetables begin to soften.
5️⃣ Add Gouda and bake: Sprinkle the shredded smoked Gouda over the vegetable mixture. Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly.
Notes
Cheese options – Substitute smoked Gouda with Gruyère or sharp cheddar for a different flavor profile.
- Storage: Allow leftovers to cool to room temperature, then store in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat in a 350°F (175°C) oven for about 10-15 minutes, or until warmed through.
