Set your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish to prevent sticking.
In a large skillet over medium heat, cook the ground beef and chopped onions for 5–7 minutes until the beef is browned and onions are soft. Drain the grease.
Stir in minced garlic, Worcestershire sauce, salt, black pepper, smoked paprika, and dried thyme. Cook for 1–2 more minutes to let the flavors come together.
In a large bowl, whisk together cream of mushroom soup, cream of tomato soup, milk, and sour cream until smooth.
Add cooked egg noodles and shredded cheddar cheese to the skillet with the beef. Pour in the sauce and mix everything until evenly coated.
Transfer the mixture to your greased baking dish and spread it out evenly.
Mix crushed buttery crackers with melted butter in a small bowl. Sprinkle the mixture evenly over the top of the casserole.
Place in the oven and bake for 30 minutes, until bubbly and golden brown on top. Sprinkle with chopped fresh parsley (optional) and serve hot.
