Ingredients

Scale

Vegetables

  • 1 large zucchini, sliced thin and cut into half circles
  • 1 small onion, sliced thin
  • 3 large cloves of garlic, minced

Dairy

  • 4 tablespoons butter
  • 1/2 cup freshly grated parmesan cheese
  • 1 cup mixed cheese (mozzarella and asiago blend)
  • 1/2 cup heavy cream

Other

  • 1/4 cup beef broth
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper

Instructions

  1. Caramelize onions and sauté garlic: In a large ovenproof skillet, melt butter over medium heat. Add the thinly sliced onions and cook until they are lightly caramelized, stirring occasionally for about 5 minutes. Add minced garlic and sauté for about 1 minute until fragrant.
  2. Add liquids and seasonings: Pour in the beef broth, heavy cream, salt, and pepper into the onion and garlic mixture. Stir thoroughly to combine all ingredients evenly.
  3. Simmer and add parmesan: Allow the mixture to begin bubbling slightly to meld the flavors. Then, stir in the freshly grated parmesan cheese until it is melted and incorporated.
  4. Incorporate zucchini and cook: Add the sliced zucchini into the skillet, distributing it evenly. Cook for approximately 5 minutes on medium heat until the zucchini softens, stirring gently to coat the slices with the sauce.
  5. Top with cheese and bake: Evenly spread your choice of shredded cheeses (mozzarella and asiago mix recommended) over the zucchini mixture. Transfer the skillet to a preheated oven at 425°F and bake for 12 to 15 minutes, or until the cheese topping is bubbling and golden brown to your liking.
  6. Serve and enjoy: Remove from oven carefully, let it cool slightly, then serve warm as a delicious low-carb side dish or light main course.

Notes

  • Use an ovenproof skillet to avoid transferring the gratin to another dish before baking.
  • Feel free to substitute beef broth with vegetable broth for a lighter flavor or to accommodate dietary preferences.
  • Adjust the salt level according to the saltiness of your cheese or broth.
  • For a vegetarian version, omit beef broth and use vegetable broth instead.
  • The cheese blend can be customized with other favorites like cheddar or Gruyere for variation.
  • Let the gratin sit for a few minutes after baking to set before serving.
