What is a key ingredient in the Spicy Marinara Sauce?

The correct answer is that crushed red pepper is a key ingredient in the Spicy Marinara Sauce. This ingredient is essential for giving the sauce its characteristic heat and spiciness, which sets it apart from traditional marinara sauces that are usually milder. Crushed red pepper enhances the flavor profile, making it appealing to those who enjoy a little kick in their dishes.

While olive oil, garlic cloves, and Parmesan cheese may be found in various marinara or pasta sauces, they do not contribute to the spicy aspect of the sauce. Olive oil is commonly used for sautéing and adding richness, garlic enhances the overall flavor, and Parmesan cheese is a popular topping but does not add spiciness. Thus, crushed red pepper is fundamental for achieving the intended spiciness in the Spicy Marinara Sauce.
