Prepare the Cabbage: Preheat your oven to 375°F (190°C). In a spacious skillet, warm the olive oil over medium heat. Sear the cabbage wedges until lightly golden on both sides. Transfer the cabbage to a greased 9x13-inch baking dish.

Make the Sauce: In the same skillet, melt the butter over medium heat. Toss in the diced onion and cook until it becomes soft and translucent. Stir in the minced garlic, Italian seasoning, and fresh thyme. Cook for another minute until fragrant. Add the heavy cream and bring it to a gentle simmer. Allow it to reduce for about 3–4 minutes.

Assemble the Dish: Stir in the shredded Gouda cheese to the cream sauce, whisking until fully melted and smooth. Pour the cheese sauce evenly over the cabbage wedges in the baking dish.

Bake: Sprinkle bacon pieces over the top and garnish with shredded Parmesan cheese. Bake in the preheated oven for 25–30 minutes, or until the cabbage is tender and the top is golden and bubbly.

Serve: Let the dish rest for a few minutes before serving. Enjoy it as a standalone main or pair it with a protein of your choice.
