Remove the chicken drumsticks from the packaging, rinse them well with cold water, and place them into a 9" x 13" baking dish.
Peel the shallots, garlic, and white onion. Dice the garlic and cut the white onions into quarters. The shallots can remain whole. The onions and shallots may break apart slightly as you put them in the baking dish, but that's ok! Add the peeled shallots, garlic, and white onion to the baking dish.
Preheat your oven to 400°F on convection bake.
Rub the chicken drumsticks with olive oil, fresh ground pepper, salt, dried oregano, garlic powder, and seasoning salt. Add 1/4 cup cold water to the pan. The water is added so that the onions and garlic don't burn at the high temperature.
Place the chicken in the preheated oven. Bake the chicken at 400°F for approximately 10 minutes. The high heat will initially sear the skin of the chicken and lock in the flavours.
While the chicken is in the oven, open the can of Italian peeled plum tomatoes and pour the whole can (including the liquid) into a bowl. Add in one tablespoon of sugar. Squish or cut the tomatoes into smaller pieces with your hands or a fork. Set aside. In a separate saucepan or tea kettle, heat about 3 cups of water so that you can easily access hot water to add to the pan as the chicken cooks.
After 10 minutes, remove the pan from the oven and flip the drumsticks over so that the other side faces up. Place the chicken back in the oven at 400°F for another 10 minutes. You may need to add a 1/4 cup of hot water to the pan if
In a separate saucepan or tea kettle, heat about 3 cups of water so that you can easily access hot water to add to the pan as the chicken cooks.
Place the chicken back in the oven at 400 degrees F for another 10 minutes. You may need to add another 1/4 cup of hot water to the pan if the bottom of the pan is drying out.
After 10 minutes (the chicken has been cooking for 20 minutes so far), remove the pan from the oven and lower the oven temperature to 350° F. Add all of the tomato sauce to the pan. Place the chicken with the tomato sauce back in the oven AT 350° F for 30 minutes.
After the chicken has been in the oven for 30 minutes, remove the pan and carefully flip the chicken over to brown the other side. Add 1/4 cup of hot water to the pan. Place the chicken back in the oven for another 20 minutes.
After 20 minutes, remove the pan from the oven. Place the golden brown chicken onto a separate plate. Cover the chicken loosely with aluminium foil and set it aside. Increase the oven temperature to 375 degrees F and 1/4 cup salted butter to the tomato sauce in the pan. Add 2 cups of hot water to the baking dish. Stir all of the ingredients together.
Place the pan back in the oven at 375°F with just the sauce (no chicken). After a few minutes, the sauce will start to boil. When adding spaghetti, the tomato sauce should be simmering or as hot as possible. Once the sauce is hot, add all of the spaghetti to the pan and stir so that the spaghetti is covered with tomato sauce.
Place the pan back into the oven at 375° F on convection bake. The spaghetti will likely need about 25-30 minutes to cook in the sauce. For best results, stir the spaghetti every 10 minutes to prevent it from sticking together or burning. When you take the dish out of the oven to stir the pasta, you can check if the pasta needs more water. Gradually add 1/4 cup of hot water to the pan if the pasta needs more water.
After the pasta is cooked, remove the pan and stir the pasta. Add the cooked chicken drumsticks back to the baking dish and bake in the oven for a few more minutes so the chicken is hot before serving. Top with grated parmesan cheese, fresh parsley or fresh basil. Enjoy!
