Rub vs. Seasoning vs. Spice Blend — What's the Difference?
Introduction
You see them side-by-side in the store: BBQ rub, seasoning, spice blend. They look alike, but they are not the same. Do you know when to use which? In this guide, we explain the difference — so you'll always know exactly what you have in your hands.
What is a BBQ Rub?
A dry rub is a dry spice mix that you apply directly to meat before grilling or smoking. The rub adheres to the surface of the meat and creates a crispy, flavorful outer layer during cooking: the bark.
A good rub consists of a balance of:
- Salt — draws out moisture and enhances flavor
- Sugar — caramelizes and adds color
- Herbs and spices — add character (paprika, cumin, garlic, pepper)
- Heat — cayenne, chili flakes, or gochugaru
At The Rub Kitchen, all our rubs are specially developed for BBQ: the ratios are tailored for high temperatures, long cooking times, and maximum bark formation.

What is a Seasoning?
A seasoning is a broader term for any spice mix you use to flavor food — before, during, or after preparation. Seasonings are not specifically designed for BBQ.
Examples:
- Italian herbs for pasta
- Cajun seasoning for fish
- All-purpose seasoning for everyday cooking
The big difference with a rub: a seasoning is rarely optimized for high heat or long cooking times. The salt/sugar/spice ratios are different — and you'll notice that on the BBQ.
What is a Spice Blend?
A spice blend (also known as a herb mix or spice mix) is the most neutral term. It is simply a combination of multiple spices. Both a rub and a seasoning are technically a spice blend — but not every spice blend is a rub or seasoning.
Spice blends are used in:
- Marinades
- Sauces
- Soups and stews
- Dry applications (such as a rub)
The Difference at a Glance
| BBQ Rub | Seasoning | Spice Blend | |
|---|---|---|---|
| Purpose | Bark & flavor on the BBQ | General flavoring | Combination of spices |
| Usage | Dry, on meat before cooking | Before, during, or after cooking | Versatile |
| Heat-resistant | Yes, specially developed | Not always | Not always |
| Salt/sugar balance | Consciously tailored for BBQ | Varying | Varying |
When Do You Use What?
Use a BBQ rub if:
- You are preparing meat, chicken, or fish on the BBQ
- You want a crispy bark
- You are smoking low & slow (spareribs, pulled pork, brisket)
Use a seasoning if:
- You want to quickly flavor something in the pan or oven
- You don't need a bark
Use a spice blend if:
- You are making a marinade, sauce, or stew
- You want to create your own rub or seasoning
Why a Good BBQ Rub Makes all the Difference
A supermarket spice mix is rarely tailored for BBQ. The ratios are incorrect, the quality of the spices is lower, and the result on the grill is disappointing.
