In a mixing bowl, add the room temperature butter, grated Parmesan cheese, minced garlic, Italian seasoning, and a generous pinch of ground black pepper.
Using a spatula or wooden spoon, mix all the ingredients together until well combined. The mixture should be creamy and smooth, with the garlic evenly distributed throughout.
Give the spread a taste and adjust the seasoning if needed. You can add more black pepper or even a pinch of salt if you prefer.
Slice your Italian bread into thick pieces, about 1 inch each. This will allow for a perfect amount of spread on each slice.
Take your Garlic Bread Spread and slather it generously on each slice of bread. Make sure to cover the surface well to ensure maximum flavor with each bite.
Preheat your oven or toaster oven to 375°F (190°C). Place the buttered bread slices on a baking sheet and toast them in the oven for about 10-12 minutes, or until the edges are golden and crispy.
Once the bread is toasted, remove it from the oven and serve immediately. Enjoy the warm, garlicky goodness on its own or as a delightful side to your favorite dishes.
