Preheat air fryer at 400 degrees for 5 minutes. Meanwhile, melt butter in microwave for up to 30 seconds.
Cut your demi baguette into cubes by cutting in half vertically, then again in half horizontally. For a smaller amount of skewers, use half to three-fourths of the demi baguette.
Toss the baguette cubes in the melted butter with 2 cloves of chopped garlic. Then, cook in air fryer for 5 minutes at 350 degrees.
While baguette is in the air fryer, prepare the balsamic vinaigrette glaze. Add remaining 2 cloves of garlic to a bowl or spout cup with balsamic glaze, raspberry vinegar, garlic salt, red pepper flakes, black pepper and fresh thyme (leaves only). Whisk well to combine.
Assemble the skewers by first taking a piece of toasted bread cubes, then a piece of fresh baby mozzarella, followed by a roasted red pepper. I like to put two layers of this combination per skewer.
Put skewers onto serving plate and drizzle with balsamic vinaigrette glaze. Then, top with sprigs of fresh thyme before serving.
