In a good-sized, oven-safe skillet, melt the butter over medium heat and gently sauté the chopped onions until they are soft and translucent.
Stir in the minced garlic, paprika, Italian seasoning, and cream cheese. Season with a pinch of salt and pepper, and stir continuously until the cream cheese melts into a smooth paste.
Pour in the heavy whipping cream and let the mixture simmer gently until it thickens into a rich, creamy sauce.
Fold in the shredded mozzarella and cheddar cheeses until melted and smooth, then carefully pour the cheese sauce out of the skillet and set it aside.
In the same skillet, arrange your fresh, nutrient-rich zucchini slices in beautiful, slightly overlapping concentric circles.
Pour the luscious cheese sauce evenly back over the zucchini layers.
Pop the skillet into the oven and bake for 20 to 25 minutes until the cheese is bubbly and golden, and the zucchini is perfectly tender.
Let this delicious dish rest for 10 minutes to set before serving!
