Best Substitutes For Red Pepper Flakes

Cayenne Pepper Powder

Cayenne pepper powder makes for a straightforward substitute for red pepper flakes, given that cayenne is often a key component of the flakes themselves. It boasts a clean, sharp heat that can rival the intensity of red pepper flakes.

The cayenne pepper is a thin chili that packs a powerful punch. When ground into a powder, it delivers a uniform heat that is easy to distribute throughout a dish, unlike the bursts of heat you might encounter with red pepper flakes. It brings a slightly fruity, piquant flavor that can add depth to a recipe.

However, it’s important to bear in mind that cayenne pepper powder is quite a bit hotter than red pepper flakes, thanks to the absence of the seeds that are typically included in the flakes. Therefore, when using cayenne as a substitute, you should start with about half the amount of red pepper flakes that the recipe calls for, and adjust according to taste.

Hot Sauce

While it may not be a direct dry spice substitute, hot sauce can provide a similar heat profile to red pepper flakes, with the added benefit of contributing moisture to a dish. Hot sauces come in a wide range of flavors and heat levels, from the tangy, mellow spice of Frank’s RedHot, to the fiery, vinegar-forward punch of Tabasco.

Choosing a hot sauce as a substitute will depend heavily on the flavor profile of the dish you’re creating. For example, a Mexican-inspired meal might benefit from a chipotle-based hot sauce, while an Asian dish could be elevated with a dash of Sriracha.

Because hot sauce brings additional liquid to your dish, it might alter the consistency of your recipe. Thus, it’s best used in dishes where a bit of extra moisture won’t be a problem, such as soups, stews, and sauces. As for the amount, this will depend on the heat level of the sauce and your personal taste, so it’s best to start with a small amount and adjust as needed.

Fresh Chili Peppers

If you’re after an alternative that can bring the raw, fresh heat of red pepper flakes, then fresh chili peppers are a great choice. From jalapenos to serranos, habaneros to Scotch bonnets, there is a broad spectrum of heat and flavor profiles available in the world of fresh chilis.

Using fresh chili peppers as a substitute brings an element of freshness that red pepper flakes and other dry spices can’t provide. They can add a vibrant pop of color and a crunchy texture that can lift a dish to new heights.

However, fresh chili peppers carry a significant amount of heat in their seeds and membranes, so removing these parts can help control the spiciness. As with any spicy ingredient, it’s always best to start with less and add more to taste.

Chili Powder

Chili powder is a blend of spices that often includes cayenne pepper, along with other ingredients like garlic powder, onion powder, and cumin. It offers a different flavor profile compared to red pepper flakes, with a more complex, savory taste.

When substituting red pepper flakes with chili powder, it’s worth remembering that its flavor can significantly alter the taste of your dish due to the mix of additional spices. So, it’s recommended to use it in recipes where these complementary flavors will enhance the overall outcome.

As for the amount to use, since chili powder is typically milder than red pepper flakes, you might need to use a bit more to achieve a similar heat level. Start with the amount the recipe requires for red pepper flakes, and adjust from there according to your taste.

Aleppo Pepper

Hailing from the Mediterranean and Middle East, Aleppo pepper offers a moderate heat level and a distinct fruitiness, with undertones of cumin and salt. It’s less spicy than red pepper flakes, but its unique flavor makes it a worthy substitute.

Aleppo pepper is often described as having a sun-dried tomato-like flavor with a slow build of heat, making it an excellent option for those who prefer a milder spice. It’s particularly suited to Mediterranean and Middle Eastern dishes, but its unique flavor can also add a twist to other types of cuisine.

While Aleppo pepper is typically harder to find than other substitutes, it’s well worth seeking out for its unique, robust flavor. Due to its milder heat, you may want to use slightly more Aleppo pepper than the amount of red pepper flakes called for in the recipe.

Szechuan Pepper

Szechuan pepper isn’t actually a pepper at all, but the dried berries of a type of ash tree. This unique ingredient is known for its tingling, numbing effect, and while it’s not as hot as red pepper flakes, it offers an intriguing flavor profile that can add a twist to your dish.

Szechuan pepper is a key component of Chinese cuisine, especially in Sichuan province, where it’s used to create the region’s characteristic “ma la” (numbing and spicy) flavor. It has a slightly citrusy flavor and creates a tingly sensation in the mouth.

When using Szechuan pepper as a substitute for red pepper flakes, it’s best suited to dishes that can accommodate its unique numbing effect and citrus notes. Start with a small amount, as its flavor can be quite potent.


Paprika, a spice made from ground, dried peppers, is generally milder than red pepper flakes. It comes in several varieties, including sweet, smoked, and hot, each providing its own unique flavor.

Hot paprika is the closest to red pepper flakes in terms of heat, but even then, it’s usually milder and sweeter. The smoky flavor of smoked paprika can add a rich depth to a dish, while sweet paprika brings a vibrant color and a mild, sweet pepper flavor.

When using paprika as a substitute for red pepper flakes, you may need to use more to reach a similar level of heat. It’s also important to consider the type of paprika you’re using, as a smoked variety will impart a very different flavor to a dish than a sweet or hot variety.
