Preheat your oven to 375°F (190°C).
Heat olive oil in a large skillet over medium heat.
Add the Italian sausage (casings removed) and ground beef to the skillet. Cook until browned, breaking up the meat into small pieces with a wooden spoon.
Remove the cooked meat and set aside on a plate. Discard any excess grease from the skillet, but leave about 1 tablespoon for sautéing the vegetables.
In the same skillet, sauté the diced onion, carrot, and celery over medium heat until softened, about 5-7 minutes.
Add the minced garlic and cook for an additional minute until fragrant.
Return the cooked sausage and beef to the skillet. Stir in the canned diced tomatoes, tomato paste, beef broth, dried thyme, oregano, salt, and pepper.
Bring the mixture to a simmer and let it cook for 10 minutes, allowing the flavors to meld together.
While the sauce simmers, boil the cubed potatoes in a pot of salted water until tender, about 10 minutes. Drain well.
Layer the cooked potatoes evenly in the bottom of a large casserole dish.
Pour the meat and vegetable mixture over the potatoes, spreading it evenly with a spatula.
If desired, sprinkle the top with shredded cheddar cheese.
Bake the casserole in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbling (if used).
Remove the casserole from the oven and let it cool for 5 minutes before serving.
Garnish with chopped parsley if desired and serve warm.
