What Are Red Pepper Flakes?

Red pepper flakes are dried and crushed pieces of hot peppers. Often found in shakers or bottles, they're used to add a punch of heat and color to dishes across many cuisines — from Italian pasta sauces to Mexican tacos and Southern fried chicken.

While many assume red pepper flakes come from a single type of pepper, the truth is more complex (and tastier!). They can be made from various chili varieties, each contributing its own unique character to the final product.

What Pepper Are Red Pepper Flakes Made From?

So, here's the burning question: what exactly goes into making those crunchy red bits? The answer depends on where you buy them and who’s making them. Here are some of the most common culprits:

• Cayenne Peppers: Known for their bright red color and medium-to-high heat, cayenne peppers are a popular base for commercial red pepper flakes.
• Crushed Red Chili Peppers: This broad term often refers to any combination of dried hot peppers — sometimes including cayenne, but also other cultivars like Thai chilies or Fresno peppers.
• Hatch Chiles: These are usually roasted before drying, adding a smoky layer to the final flake.
• Bird’s Eye Chilies: Common in Southeast Asian blends, these deliver a sharper, more aggressive heat than traditional American-style flakes.
• Mixed Blends: Some artisanal brands create proprietary mixes using multiple peppers for balanced heat and flavor complexity.

Now that you know the players, let’s talk about how they stack up in terms of flavor and fire!

Heat Level & Flavor Profile

One of the best things about red pepper flakes is that you can find versions with wildly different flavor notes and spice levels depending on the source pepper. Let’s break down what to expect:

Pepper Type	Scoville Heat Units (SHU)	Flavor Notes	Best For
Cayenne	30,000 – 50,000	Earthy, slightly sweet, sharp bite	Pasta, soups, marinades
Fresno	2,500 – 10,000	Slightly fruity, smoky when roasted	Tacos, burgers, chili oil
Thai Bird’s Eye	50,000 – 100,000	Very bright, grassy, intense	Asian stir-fries, curries
Hatch Green Chile	Varies by roast level	Smoky, earthy, slightly vegetal	Southwestern cuisine, enchiladas
Mixed Artisan Blend	10,000 – 70,000	Complex, layered flavors	Chef’s choice dishes, gourmet meals

As shown above, red pepper flakes aren’t a one-size-fits-all seasoning. Depending on your preference, you can go bold and fiery or mellow and smoky.

Pro Tips for Using Red Pepper Flakes

If you’re ready to take your culinary game to the next level with red pepper flakes, here are some tried-and-true techniques to make the most out of this versatile spice:

1. Toasted for More Flavor: Lightly toast flakes in a dry pan for 30 seconds to unlock deeper aromas. Perfect for sprinkling over rice bowls or grain salads.
2. Make Your Own Chili Oil: Combine red pepper flakes with oil and garlic for an easy homemade condiment. Store in the fridge for up to 2 weeks.
3. Add at the End for Maximum Kick: If you want a punch of heat, sprinkle flakes onto finished dishes like pizza, noodles, or grilled meat.
4. Use Sparingly in Baking: Believe it or not, red pepper flakes can add a surprising depth to chocolate desserts or spiced cookies.
5. Infuse in Broths or Marinades: Simmering red pepper flakes into broths gives a subtle background warmth without overwhelming the dish.
6. Pair With Sweet Ingredients: Think honey, citrus, or mango — the contrast between sweet and spicy creates a delicious balance.

These simple tricks can transform your everyday cooking into something truly memorable.

Buying Guide: Choosing the Best Red Pepper Flakes

With so many options lining the shelves of grocery stores and specialty shops, how do you choose the right red pepper flakes for your needs? Here's a breakdown of key considerations:

• Whole vs. Crushed: Whole dried chilies can be crushed at home for fresher flavor. Pre-crushed flakes are convenient but may lose potency faster.
• Ingredient List: Read labels! Some commercial products contain fillers like salt or anti-caking agents. Pure crushed pepper is ideal.
• Brand Reputation: Artisan brands often offer better quality and flavor clarity. Look for companies that disclose the pepper types used.
• Organic Certification: Organic flakes ensure no chemical residues, especially important if you're using them liberally.
• Origin Matters: Mexican, Indian, or Korean red pepper flakes often come from region-specific cultivars and offer distinct flavor profiles.
• Storage Tips: Keep red pepper flakes in a cool, dark place in an airtight container to preserve color and heat. Shelf life is typically 6–12 months.
