Ingredients

Scale

Main Ingredients:

  • 1 small zucchini, sliced into rounds ⅛ to ¼ inch thick (about 150 grams)
  • 1 small yellow squash, sliced into rounds ⅛ to ¼ inch thick (about 150 grams)
  • ½ onion, thinly sliced

Dairy and Cream:

  • 1 cup shredded smoked gouda (100 grams)
  • ¼ cup grated parmesan (25 grams)
  • 2 tablespoons butter (28 grams)

Aromatics:

Instructions

  1. Ignite the oven to a scorching 450°F, preparing a searing environment for the vegetable medley.
  2. Melt butter in a cast-iron skillet, allowing it to shimmer over medium heat until golden.
  3. Introduce sliced onions to the skillet, caramelizing the edges until they develop a rich, amber hue.
  4. Infuse the pan with minced garlic, stirring briefly to release its aromatic essence.
  5. Stream heavy cream into the skillet, coaxing it to bubble and thicken with gentle swirls.
  6. Gradually fold parmesan cheese into the cream, creating a velvety, luxurious sauce.
  7. Layer thinly sliced zucchini and yellow squash into the creamy base, allowing them to nestle and soften.
  8. Blanket the vegetables with a generous shower of smoked gouda, ensuring even coverage.
  9. Slide the skillet into the heated oven, transforming the dish with intense heat for 15-20 minutes.
  10. Watch for the cheese to melt into a golden, bubbling crust signaling the gratin’s perfect completion.
  11. Extract from the oven, letting the dish rest momentarily before serving this rustic, creamy vegetable masterpiece.

Notes

  • Opt for fresh, firm zucchini and yellow squash for the best texture and flavor in this creamy gratin.
  • Use an oven-proof skillet to minimize dish cleanup and ensure seamless cooking from stovetop to oven.
  • Caramelize onions carefully to develop a rich, sweet undertone that complements the vegetables’ mild taste.
  • Choose a high-quality smoked gouda for an extra layer of depth and complexity in the dish.
  • Allow the gratin to rest for a few minutes after baking to help the cream sauce set and make serving easier.
  • This dish pairs perfectly with grilled proteins or can be enjoyed as a standalone vegetarian main course.
