Skip to Step 4 if keeping the skin on the tomatoes. Optional: Fill pot with water and heat on high heat. Wash the tomatoes and score the bottoms making an x-shape with a small knife. Add the scored tomatoes to pot once water is boiling and turn down heat to medium high heat.
Optional: Make an ice bath while tomatoes are in the pot. Boil tomatoes for about 2 to 3 minutes. Remove tomatoes from heat and place in the ice bath. (Optional: save the ice bath water for the pot to boil your pasta noodles.)
Optional: Peel the skin off the tomatoes. The skin will come off easily.
Cut the tomatoes into ½ inch x ½ inch pieces. Place in a large bowl and set aside.
Heat a 5-quart large fryer pan or 11” saucepan on medium heat.
Once the pan is heated, add olive oil and heat for 30 seconds.
Add the garlic slices to pan and sauté for 1 minute. Add Italian seasoning, salt, pepper, and tomatoes and stir to combine.
Turn the heat up to high and cook for 10 minutes on high, stirring occasionally. The sauce will thicken as it boils.
Turn the heat down to low. Add ¼ cup unsalted butter or olive oil to sauce. (Optional: If serving with shrimp, add 1 pound of peeled and deveined shrimp and cook for 2 to 3 minutes in sauce.)
Add your favorite cooked pasta (1 lb when uncooked/dry) to the sauce to finish cooking in the sauce. If not using shrimp, serve with cooked and sliced Italian sausage links.
