Ingredients you’ll need
- 350 grams of spaghetti
- 1 red bell pepper, finely chopped
- 1 onion, finely chopped
- 2 cloves garlic, minced
- 1 heaping tablespoon of flour
- 300 ml chicken stock
- 200 ml heavy cream
- 50 grams unsalted butter
- 100 grams grated Parmesan cheese
- 100 grams grated cheddar cheese
- Fresh parsley, chopped
- Salt and pepper, to taste
Step-by-step Instructions
- Bring a large pot of salted water to a boil. Cook the spaghetti until al dente according to the package instructions. Reserve 1/2 cup of cooking water, then drain.
- While the pasta cooks, melt the butter in a large skillet over medium heat. Add the onion and red bell pepper with a pinch of salt. Cook until the vegetables soften and the onion is translucent—about 5 minutes.
- Add the minced garlic. Cook for another minute, stirring, until fragrant. Sprinkle the flour over the vegetables and stir well for one minute to make a light roux.
- Gradually pour in the chicken stock, whisking to combine. Then add the heavy cream. Let this mixture simmer for 3–4 minutes until slightly thickened and glossy.
- Prefer vegetarian? Swap chicken stock for veggie stock.
- For a twist, use whole wheat or gluten-free pasta.
- Make it heartier—add cooked chicken, shrimp, or crispy bacon.
