Put all ingredients (except for the grated cheese, bacon, and some extra basil for garnish) in a large pan and add the water.
12 ounces spaghetti, 1 (dry) pint grape tomatoes, halved, 3 large leaves of basil, roughly chopped, 1 shallot, chopped, 4 cloves garlic, finely chopped, 1 teaspoon hot pepper flakes, 2 tablespoons extra virgin olive oil, 1 teaspoon salt (add more to taste), ½ teaspoon black pepper, 1 tablespoon tomato paste, 1 anchovy, 1 Knorr beef bouillon cube, 4 cups water (add more as needed)
Bring to a boil, and while frequently tossing the ingredients, cook in bubbling water for 10 minutes or so. You want the pasta to be al dente and the liquid to be mostly absorbed and evaporated. The starch from the pasta will create a nice, creamy sauce. Add water if it evaporates too quickly.
Serve on a plate, add the grated cheese and bacon bits, and top it with a couple basil leaves.
4 slices cooked bacon, cut into bits (optional), Parmigiano-Reggiano, freshly grated
This is a good time to bring out your top-shelf extra-virgin olive oil and sprinkle some over the whole dish.
Tip: If you want to sauté the garlic, shallots, anchovy, and tomato paste first in the olive oil for a couple of minutes, that will give your dish even more depth. But I wanted to keep the instructions as simple as possible and as a one-pan, one-cooking-step kind of recipe.
