The Spice Dilemma: What’s the Difference Anyway?
If you’ve ever stood in front of the spice aisle scratching your head over whether to grab chili flakes or red pepper flakes, you’re not alone. Visually, they often look similar—both are bits of dried, crushed chilies. But dig a little deeper (and taste a little harder), and you’ll find key differences that can change the flavor and heat of your dish entirely.

What Are Chili Flakes?
Chili flakes are typically made from a variety of dried chilies—often including cayenne, Thai, or other regional peppers—and may contain seeds and varying pod pieces. These flakes pack a punch, offering both heat and depth of flavor depending on the type of chilies used.
- Flavor profile: Smoky, earthy, sometimes fruity with moderate to high heat.
- Common usage: Italian dishes like marinara sauces, Asian stir-fries, and hot oils.
- Heat level: Varies widely, usually between 30,000–50,000 Scoville units depending on the blend.

What Are Red Pepper Flakes?
Red pepper flakes, by contrast, are more standardized. In the U.S., especially, the term “red pepper flakes” usually refers to a specific product made primarily from Capsicum annuum varieties like cayenne or California chiles. They tend to be uniform in texture and spiciness compared to generic chili flakes.
- Flavor profile: Mildly smoky with a sharp, consistent heat.
- Common usage: Pizza, pasta, soups, and as a table condiment.
- Heat level: Moderate heat, around 30,000–40,000 Scoville units.
