Ingredients

1 pound penne pasta
6 slices bacon
1 cup bread crumbs
1/4 cup butter, melted
2 tablespoons chopped fresh parsley
3 tablespoons olive oil
6 cloves garlic, finely chopped
3 medium carrots, finely chopped
2 tablespoons all-purpose flour
4 cups heavy cream
1 teaspoon chopped fresh thyme
1 cup shredded Monterey Jack cheese
2 cups shredded sharp cheddar cheese
1/2 teaspoon black pepper
3 cups cooked leftover prime rib chunks

How To Make prime rib casserole

Step 1

Preheat oven to 350 degrees F.

Step 2

Fill a large pot with lightly salted water and bring to a rolling boil over high heat. Once the water is boiling, stir in the penne. Return to a boil. Cook the pasta uncovered, stirring occasionally, until the pasta has cooked through but is still firm to the bite, about 11 minutes. Drain well.
Step 3

Place the bacon in a large, deep skillet. Cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Transfer the bacon slices to a paper towel-lined plate. Reserve the remaining drippings in a small bowl.
Step 4

Crumble the bacon and add to another small bowl. Add in the bread crumbs, butter, and chopped parsley. Mix and set aside.
Step 5

Wipe out the skillet, add the olive oil, and heat over medium heat. Stir in the garlic and carrots and saute about 5 minutes.
Step 6

Stir in the bacon drippings and flour. Cook while stirring about 1 minute.
Step 7

Whisk in the heavy cream and thyme. Continue to cook while stirring until reduced by 1/3.
Step 8

Add the cheeses and stir until melted. Season with pepper.
Step 9

Stir in the prime rib chunks and cooked pasta.
Step 10

Transfer the mixture to a 9x13-inch baking dish. Sprinkle with the bread crumb mixture.
Step 11

Bake until the bread crumbs are browned and the sauce is bubbly, about 25 minutes.
