Pre-heat oven to 350 degrees.
First, fill up the pot with water and bring to a boil.
Second, once the water is boiling, add a generous amount of salt and the spaghetti noodles. (I like to break the noodles in half to make them fit into the pot and to make the dish easier to serve and eat.)
Third, let the noodles cook according to the directions while you go to the next step. (When the noodles are done cooking, drain them.)
Now, brown the ground deer meat.
Then, add onion and garlic powder, dried basil leaves, and Tony's seasoning to the browned meat.
Next, let the seasonings, spices, and meat heat up, but just be careful to not let the garlic powder burn.
Add the Rotel and the marinara sauce to the browned meat and spices and bring to a simmer.
Once the sauce and meat have been heated thoroughly, turn off the heat and move to the next step.
Place cream cheese and milk into a microwaveable bowl and melt.
Then, stir the parmesan cheese, garlic, and onion powder into the cream cheese mixture and set aside.
Place just enough meat sauce on the bottom of the baking dish to keep the noodles from sticking.
Pour drained spaghetti noodles into the baking dish.
Next, spread the cream cheese mixture on top of the spaghetti noodles and mix.
Then, pour meat sauce on top of the spaghetti noodles and mix.
Sprinkle with parmesan cheese.
Cover the top with mozzarella cheese.
Bake at 350 degrees until cheese is melted and spaghetti bake is heated thoroughly. (About 30 minutes)
