What Exactly Are Red Pepper Flakes?

At first glance, red pepper flakes look like just tiny bits of dried chili peppers. But there’s more than meets the eye! These little crimson pieces pack a punch of heat and flavor, making them a go-to ingredient in many cuisines around the world — especially Italian, Mexican, and Asian dishes.

They’re typically made by drying out hot peppers and then crushing or flaking them into small pieces. The result? A versatile spice that adds heat without overpowering other flavors. Whether you're cooking pasta, stir-frying veggies, or grilling meat, a pinch (or a generous sprinkle) of red pepper flakes can elevate your dish from bland to bold.

Which Pepper Is Used in Red Pepper Flakes?

Now here's where things get spicy — literally. While some brands may blend different types of chilies for complexity, most red pepper flakes are primarily made from cayenne peppers or similar hot peppers like Thai chilies or bird’s eye chilies.

Pepper Type	Heat Level (Scoville Units)	Taste Profile
Cayenne	30,000–50,000	Earthy, slightly smoky, with a lingering heat
Thai Chili	50,000–100,000	Sharp, bright, and intense heat with fruity notes
Bird's Eye Chili	100,000–225,000	Very hot, with a grassy, almost citrus-like flavor
Jalapeño (sometimes included)	2,500–8,000	Mildly spicy with vegetal undertones

So when someone asks, "What pepper is red pepper flakes made from?", the short answer is usually **cayenne** — but don’t be surprised if your favorite brand mixes in other peppers for added depth and kick!

Common Uses of Red Pepper Flakes in Cooking

One of the reasons red pepper flakes are so beloved is their versatility. They can be tossed into nearly any savory dish to add warmth and complexity. Here are some popular ways to use red pepper flakes:

• Pasta Sauces: Especially in arrabbiata sauce, red pepper flakes bring heat to the tangy tomato base.
• Pizza & Flatbreads: Sprinkle over your homemade pie before or after baking for a zesty finish.
• Stir-Fries: Toss in at the beginning or end of cooking depending on how much heat you want infused.
• Marinades & Rubs: Mix with olive oil, garlic, herbs, and salt for a fiery rub for meats or veggies.
• Dips & Dressings: Add a pinch to mayo, aioli, vinaigrettes, or hot sauces for extra kick.

Red Pepper Flakes vs. Other Chilies: What’s the Difference?

You might wonder how red pepper flakes compare to fresh chilies, crushed red pepper, or even chili powder. Here’s a breakdown to help you understand the differences:

Type	Form	Heat Level	Flavor Notes	Best Use
Red Pepper Flakes	Dried, crushed	Moderate to high	Earthy, smoky, long-lasting burn	Sauces, oils, soups, marinades
Fresh Chilies (e.g., Jalapeño)	Fresh or pickled	Low to moderate	Vegetal, crisp, quick bite	Garnishes, salsas, tacos
Crushed Red Pepper	Dried, finer grind	High	Similar to flakes but more intense	Spicy dressings, dry rubs
Chili Powder	Ground mix of spices	Moderate	Smoky, earthy, with paprika and cumin notes	Tacos, chili con carne, Tex-Mex dishes

The key takeaway? Red pepper flakes are great for infusing dishes with steady heat and texture, while fresh chilies give a sharper, briefer spice burst.

Buying Guide: How to Choose the Best Red Pepper Flakes

Not all red pepper flakes are created equal. Here’s how to pick the right ones for your taste buds and cooking style:

Check the Label

• Ingredients: Ideally, the label should only list “crushed red pepper” or “red pepper flakes.” Avoid blends with fillers or artificial additives unless desired.
• Country of Origin: Some top producers include the USA (especially California-grown), India, and Mexico.
• Whole Seeds vs. Seedless: Seeds carry more heat. If you prefer a milder flavor, opt for seedless varieties.

How to Store Red Pepper Flakes Like a Pro

Proper storage ensures your red pepper flakes keep their flavor and potency for months. Here’s how to do it right:

• Airtight Container: Transfer flakes to a sealed glass jar or plastic container to prevent moisture absorption.
• Keep It Cool & Dark: Store in a cool pantry away from sunlight. Heat and light degrade the essential oils that give flavor and heat.
• Freeze for Longevity: For maximum shelf life (up to 2 years), store in a freezer-safe bag or container.
