Homemade BBQ Sauce Recipe from Grandma

There is no better way to begin Mother’s Day weekend than by making my Grandma’s Homemade BBQ Sauce recipe with my parents and my sister. This is one of those family recipes that carries more than flavor. It carries memories, stories, and the feeling of gathering around the kitchen together.

The original recipe came from a handwritten index card that my mom lovingly described as “very seasoned.” It has clearly been used many times, which makes it even more special.

We stayed true to the original homemade BBQ sauce recipe, but we made a few small updates for clarity. The instructions are more detailed, and the bottle sizes are listed so the recipe is easier to follow at home.

BBQ sauces can vary so much from one recipe to another. Some are smoky, some are honey-sweet, and others bring plenty of heat. This one is a sweet and tangy BBQ sauce with a classic homemade flavor that works beautifully with chicken, pork, ribs, and more.

From what my family has told me, this sauce was well known in the small Kentucky town where my mom grew up. My mom and aunts remember people asking for Grandma’s BBQ sauce recipe and talking about how good it was.

I have wonderful childhood memories of watching my mom make this sauce from that original recipe card. Once it was ready, the whole family would enjoy it on ribs, chicken, and even pieces of bread dipped right into the sauce. The food was delicious, but the best part was hearing everyone talk about Grandma and the memories tied to her cooking.

This was our big day making the legendary family BBQ sauce together. It felt meaningful to bring the recipe back to life as a family and share it again in Grandma’s honor.

I hope we made you proud, Grandma.

How to Make Grandma’s Homemade BBQ Sauce

Start with a large pot set over medium to medium-low heat. Add olive oil and two diced onions. The goal is to cook the onions until they are soft and tender, not browned.

This step takes a little patience. Let the onions cook for about 12 to 15 minutes, stirring a few times as they soften. If they begin to brown, lower the heat slightly. The onions create a flavorful base for this sweet and tangy homemade BBQ sauce.

Next, season the onions with kosher salt, garlic powder, and onion powder. The original recipe used garlic salt and onion salt, but using the powders along with kosher salt makes it easier to control the overall salt level.

Once the onions are soft and seasoned, the rest of the sauce comes together easily. Add a bottle of chili sauce, a bottle of ketchup, sugar, water, white vinegar, Worcestershire sauce, yellow mustard, and prepared horseradish.

Bring the mixture to a gentle simmer and let it cook over medium-low heat for at least one hour. Stir it occasionally as it bubbles. The longer simmer helps the flavors blend into a smooth, rich, classic BBQ sauce.

Taste and Adjust Grandma’s Homemade BBQ Sauce

As with any homemade sauce, always taste it before serving. Add more kosher salt, garlic powder, onion powder, Worcestershire sauce, or any of the seasonings already in the recipe if you want to adjust it to your taste.

This homemade BBQ sauce is delicious brushed over grilled chicken, spooned onto pulled pork, served with ribs, or used as a dipping sauce. It is sweet, tangy, and full of old-fashioned family flavor.

This is also a great recipe to double. If you have leftovers, freeze the sauce in covered containers and enjoy it later. It is an easy way to keep homemade BBQ sauce ready for future dinners, cookouts, grilling nights, or family meals.

Thank you, Grandma, for sharing such a wonderful recipe. It is simple, nostalgic, and still just as special today.
