Instructions

• Preheat your oven to 350°F. You’ll need it ready for later baking step.
• Cook your rotini pasta till it’s just al dente according to package directions. You wanna drain it and set it aside to keep that texture nice.
• Next, heat olive oil in a skillet over medium heat. Toss in your chopped onions and garlic and cook till onions get translucent and smell yummy.
• Now add your ground beef to the skillet. Brown it up, breaking apart as it cooks evenly. Season it with salt and black pepper while you do this.
• Stir in tomato paste and diced tomatoes. Mix it all good till everything’s combined and smells fantastic.
• Then add your Dijon mustard and cooked pasta to the skillet mix. Stir well so every bite will have all those flavors together.
• Transfer everything to a greased 9x13 baking dish, then pop it in the oven for 20 to 25 minutes or till it’s fully heated through.
• Once it’s ready, serve that cheeseburger casserole hot and enjoy every bite.
