Italian sausage is not inherently spicy. It comes in two main varieties: sweet (mild) and hot. The sweet variety contains no spicy ingredients, while the hot variety includes red pepper flakes or other spices for a noticeable kick. According to the Italian Food Association, traditional Italian sausage recipes typically do not include spicy elements. However, American-Italian versions often offer a 'hot' variety with added heat.
Types of Italian Sausage
Italian sausage has two primary varieties with distinct spice profiles:
- Sweet Italian Sausage: Also known as mild Italian sausage, this variety contains no spicy ingredients. It's seasoned with garlic, fennel, and black pepper. Traditional Italian recipes use this style, which has no measurable heat (0 SHU on the Scoville scale).
- Hot Italian Sausage: This variety includes red pepper flakes, cayenne pepper, or hot paprika, giving it a noticeable kick. Hot Italian sausage typically ranges from 500-2,000 SHU (Scoville Heat Units), comparable to mild jalapeños. It's primarily an American-Italian adaptation.
Type | Spice Level | Key Ingredients | Best Uses |
---|---|---|---|
Sweet Italian Sausage | Mild (0-500 SHU) | Garlic, fennel, black pepper | Pasta dishes, meatballs, stews |
Hot Italian Sausage | Medium (500-2,000 SHU) | Red pepper flakes, cayenne, paprika | Pizza, chili, grilled meats |

How to Identify Spice Levels
- Check packaging labels: Look for "sweet", "mild", or "hot" designations. Reputable brands like Boar's Head or Applegate clearly label spice levels.
- Examine ingredients list: If red pepper flakes, cayenne, or paprika appear in the ingredients, it's the hot variety.
- Ask butchers directly: When purchasing fresh sausage, ask "Is this sweet or hot?" to confirm the spice level.

What's the difference between sweet and hot Italian sausage?
Sweet Italian sausage contains fennel and other aromatic herbs but no spicy ingredients, while hot Italian sausage includes red pepper flakes or other spicy elements. Despite the name "sweet," it's not sugary—it refers to the mild, herb-forward flavor profile. The hot variety provides a noticeable kick while maintaining the characteristic fennel and garlic notes.
Can I make mild Italian sausage spicy at home?

Which Italian sausage is best for pizza?
Hot Italian sausage is traditionally used on pizza for its spicy kick that complements tomato sauce and cheese. However, sweet Italian sausage is also popular, especially for those who prefer milder flavors.
