Cheeseburger macaroni

• 8 ounces medium pasta shells
• 1 pound ground beef
• 2-3 tablespoons onion, diced
• Pinch garlic powder 
• 1 1/2 teaspoons Italian seasoning
• 2 tablespoons all-purpose flour
• 1 3/4 cups beef stock
• 1 (15-ounce) can tomato sauce
• 3/4 cup heavy cream
• Kosher salt and freshly ground black pepper, to taste
• 8 ounces shredded extra-sharp cheddar cheese

DIRECTIONS:

1. In a large pot of boiling salted water, cook pasta according to package instructions; drain well.
2. Heat large skillet over medium high heat. Add ground beef and cook until browned, about 3-5 minutes, making sure to crumble the beef as it cooks; drain excess fat. Set aside.
3. Add onion to the skillet, and cook, stirring frequently, until translucent, about 2-3 minutes. Stir in Italian seasoning until fragrant, about 1 minute.
4. Whisk in flour until lightly browned, about 1 minute.
5. Gradually whisk in beef stock and tomato sauce. Bring to a boil; reduce heat and simmer, stirring occasionally, until reduced and slightly thickened, about 6-8 minutes.
6. Stir in pasta, beef and heavy cream until heated through, about 1-2 minutes; season with salt and pepper, to taste. Stir in cheese until melted, about 2 minutes.
7. Serve immediately.
