How to Make Cheesy Zucchini Gratin! (Low Carb)

Now that you have your ingredients ready, let’s dive into the steps to create this mouthwatering Cheesy Zucchini Gratin! (Low Carb). Follow along, and I promise you’ll have a dish that’s both comforting and delicious!

Step 1: Sauté the Onions and Garlic

Start by melting the butter in a large oven-proof skillet over medium heat. Once it’s melted, toss in the thinly sliced onions. Sauté them until they turn a lovely golden brown, which usually takes about 5 minutes. This caramelization adds a sweet depth to the dish.

Next, add the minced garlic and stir for about a minute. The aroma will fill your kitchen, making it hard to resist sneaking a taste!

Step 2: Prepare the Creamy Mixture

Once the onions and garlic are perfectly sautéed, it’s time to create that creamy goodness. Pour in the beef broth, followed by the heavy cream, salt, and pepper. Stir everything together until well combined.

Let this mixture bubble gently for a minute. Then, sprinkle in the freshly grated parmesan cheese. Stir until the cheese melts and the mixture becomes creamy and luscious.

Step 3: Combine Zucchini and Mixture

Now, it’s time to add the star of the show—our sliced zucchini! Gently fold the zucchini into the creamy mixture. Cook for an additional 5 minutes, allowing the zucchini to soften slightly. This step ensures that every bite is infused with that cheesy goodness.

Step 4: Add Cheese and Bake

Finally, it’s time to top it all off! Sprinkle your choice of cheese evenly over the zucchini mixture. I love using a mix of mozzarella and asiago for that perfect melt.

Preheat your oven to 425°F (220°C) and pop the skillet in. Bake for about 12-15 minutes, or until the cheese is bubbly and golden brown. Keep an eye on it; you want that perfect cheesy crust!

Once it’s out of the oven, let it cool for a few minutes before serving. Trust me, the anticipation will be worth it!

Tips for Success

  • Slice the zucchini thinly for even cooking and a tender bite.
  • Don’t skip the caramelization step; it adds incredible flavor!
