Preheat the oven to 400 degrees F.
Place the blade attachment onto the food processor. Add the sun-dried tomatoes, walnuts, cheese, garlic, oregano, parsley and ¼ cup of the sun-dried tomato oil to the food processor. Pulse until the mixture is smooth, adding additional oil until the mixture is flowing smoothly, but not oily. You don’t want oil standing as a traditional pesto would have.
Soften the butter in a medium bowl in the microwave. It’s fine if the butter is partly melted.
Scrape the Pesto into the bowl with the butter. Add the parsley, garlic, Aleppo Pepper, Black Garlic Sea Salt, black pepper, and the cheese. Combine well. Taste and adjust any seasoning as needed. Set aside.
Cut 1” slices into the loaf/baguette, but not cutting through the bottom; you want the whole loaf still attached on the bottom so that the slices will hold the filling in.
Place the loaf onto a large piece of heavy duty aluminum foil.
Evenly divide the sun-dried tomato filling in between the slices. A soup spoon does well for this.
Wrap the foil around the loaf, sealing all the edges. Bake in the oven for 15 minutes.
Remove from the oven. Unwrap the top part of the foil to expose the top of the loaf.
Bake for another 5 to 8 minutes, or until nicely browned and the cheese is melted.
Remove from the oven. You may slice/cut the slices apart or allow guests to pull the bread apart.
The bread is best when baked and served immediately, while still warm. The Sun-dried Tomato Pesto may be made and refrigerated up to 2 days in advance. Allow the butter to soften at room temperature or for about 5 seconds in a microwave.
