Sheet Pan Meatballs and Sausage

2 T. olive oil

1 onion, finely chopped

4 cloves garlic, minced

2 tsp. dried oregano

1/4 tsp. red pepper flakes

4 slices hearty white sandwich bread

3/4 C. milk

1 lb sweet Italian sausage links

1 C. parmesan cheese, grated

1/2 C. chopped fresh parsley leaves

2 large eggs

2 cloves garlic, minced

1 1/2 tsp. salt

2 1/2 lb. ground beef chuck

 

Heat oil in a large skillet over medium-high heat. Cook onions until golden, 10 to 15 minutes. Add garlic, oregano, and pepper flakes and cook until fragrant, about 30 seconds. Transfer to a large bowl to slightly cool.   Meanwhile, adjust oven rack to upper-middle position and preheat oven to 475 degrees. Mash the bread and milk with the onion mixture.  Remove the casings from two of the sausage links and add to the bread mixture along with the parmesan, parsley, eggs, garlic, and salt.  Mix well with your hands to combine.  Add the ground beef and knead with your hands until well combined. Form mixture into 2 1/2-inch meatballs (you should have about 16 meatballs), and place on rimmed baking sheet.  Arrange the remaining sausages around the meatballs and bake until well browned, about 20 minutes. Once your meatballs and sausage are cooked, you can transfer them to your favorite sauce to simmer for a bit and add flavor to it, fill some hoagie rolls with them and top with mozzarella, or freeze for later use!
