Preheat the oven to 375 degrees Fahrenheit. Slice 1 large head green cabbage into 8 wedges, keeping the core intact on each wedge.
Heat a large oven safe skillet over medium-high heat. Add 2 tablespoons olive oil. Once the oil is hot, add the cabbage and sear for 2-3 per side, until the cabbage has a nice golden crust. Remove to a plate and season with salt and pepper to taste.
To the same skillet, over medium heat, add 2 tablespoons butter. Once the butter is melted, add ½ cup diced yellow onion and 3 teaspoons minced garlic. Cook for 3-4 minutes until the onions begin to soften.
Add 1 cup chicken broth to the skillet to deglaze, scraping up any brown bits. Add 4 ounces cream cheese and whisk until fully melted and smooth.
Add 1 cup heavy cream, ½ cup chopped sundried tomatoes, 2 teaspoons Italian seasoning, and ½ cup grated parmesan. Whisk until combined. Let the sauce simmer until it thickens slightly; this will take about 2-3 minutes. Remove from heat.
Add the cabbage wedges back into the skillet, nestling them together until they all fit. Spoon some sauce over the top of the cabbage.
Cover with foil and bake for 45 minutes. Remove the foil and spoon more sauce over the top, basting the cabbage. Bake for an additional 15-20 minutes, until tender and golden.
