Making Beer Brat and Caramelized Onion Pizza can be straightforward if you follow these simple steps:

1. Preheat your oven to 475°F (245°C). If you have a pizza stone, place it in the oven to heat up.
2. Cook the Sausages: In a skillet over medium heat, cook the beer brat sausages until browned and cooked through, about 10-12 minutes. Remove from heat and slice them into bite-sized pieces.
3. Caramelize the Onions: In the same skillet, add olive oil and sliced onions. Stir occasionally over medium-low heat until they are golden brown and caramelized, about 15-20 minutes. Season with salt and pepper.
4. Prepare the Pizza Dough: Roll out the pizza dough on a floured surface to your desired thickness. Transfer it to a pizza peel or baking sheet lined with parchment paper.
5. Add the Sauce and Cheese: Sprinkle half of the mozzarella cheese over the dough. Next, evenly distribute the sliced beer brats and caramelized onions on top. Finish with the remaining mozzarella and cheddar cheese.
6. Bake the Pizza: Carefully slide the pizza onto the preheated pizza stone (or place the baking sheet in the oven). Bake for 12-15 minutes or until the cheese is bubbly and the crust is golden brown.
7. Drizzle with Mustard: Once the pizza is out of the oven, let it cool for a few minutes. Drizzle mustard over the top for an added zing.
8. Garnish: Sprinkle freshly chopped parsley on top for a pop of color and freshness.
9. Slice and Serve: Use a pizza cutter to slice the pizza into wedges and serve warm.
