Ingredients:
- 3 medium zucchini (sliced into 1/4″ thick slices) (approx. 400g or 0.88lb)
- 3/4 tsp sea salt
- 1 1/2 cup Swiss Gruyere shredded cheese blend (or any shredded sharp cheese; divided) (approx. 170g or 6oz)
- 1/4 tsp black pepper
- 3 oz. Brie cheese (edges cut off) (approx. 85g)
- 1/3 cup heavy cream (approx. 80ml)
- 1 tbsp. unsalted butter (approx. 15g)
- 2 cloves garlic (minced or crushed)
- 1/2 tbsp. Italian seasoning
Directions:
Start by prepping the zucchini. Slice them into 1/4″ thick slices and toss them with 3/4 tsp of sea salt. Place them in a colander and let them drain over the sink for about 45 minutes. Once the time is up, pat the slices dry with a paper towel.
Preheat the oven to 400 degrees F (204 degrees C).
In a small 1.5 quart (1.5 L) casserole dish, arrange the zucchini slices in several overlapping rows, lightly sprinkling each layer with shredded cheese. Alternate layers of zucchini and cheese until the entire baking dish is filled. You’ll use about 3/4 cup (half of the total) cheese altogether. Season lightly with black pepper.
In a small saucepan, combine the brie, heavy cream, butter, and garlic. Heat the mixture on the stove over low to medium-low heat, stirring frequently, until the cheese is melted and the mixture is smooth. If desired, add a pinch of sea salt to taste.
Pour the cheese mixture evenly over the zucchini.
Sprinkle the remaining 3/4 cup of shredded cheese blend on top. Top with Italian seasoning.
Bake for about 20-25 minutes, until the cheese on top is dark golden brown and the zucchini is soft.
Let the casserole cool for a few minutes before serving. Enjoy!
Notes:
- If you don’t have Gruyere cheese, you can substitute it with any other type of shredded sharp cheese.
- Make sure to slice the zucchini into even slices so that they cook evenly.
- This casserole can be reheated in the oven or microwave, but it’s best served fresh out of the oven.
