This is delicious carbonara, fairly quick.
Operating on a strict single-serving budget requires minimizing waste across every component, meaning standard pantry staples must pull double duty without unnecessary extravagance. Fettuccine anchors the bowl, though spaghetti or bucatini can substitute at a direct one-to-one ratio with identical boiling times. Heavy cream replaces the traditional emulsified egg-and-cheese mixture found in Roman classics, introducing a stable dairy fat that resists curdling when tossed over residual heat. Rendering the bacon over medium-low heat extracts maximum rendered fat without burning the delicate milk solids, yielding crisp lardons and leaving precisely enough grease in the skillet to sweat the onions. Thinly sliced garlic requires only thirty seconds in the hot pan until aromatic; exceeding that window turns the cloves bitter and overpowers the mild sweetness of frozen peas. Salting the pasta water generously ensures proper seasoning penetrates the interior of the noodle during the ten-minute boiling window rather than relying solely on post-pour seasoning. Pair this rich, pork-heavy dish with a crisp, high-acidity white wine like Pinot Grigio or a bitter green salad dressed simply in lemon juice and olive oil to cut through the heavy cream and salty bacon fat.
