Smokehouse BBQ Sauce
Rich tomato. Balanced sweetness. Bright tang. Just enough smoke and heat.
A homemade barbecue sauce built from crushed tomatoes, fresh onion and garlic, apple cider vinegar, apple juice, brown monk fruit sweetener, and Firehouse Seasoning.
No tomato sauce. No tomato paste. No liquid smoke.
Just real ingredients given enough time to turn into a rich, flavorful barbecue sauce.
Great barbecue comes first.
Around here, great barbecue doesn't depend on sauce.
It starts with quality meat, good seasoning, smoke, and enough patience to let time do its job.
When the meat is cooked right, sauce becomes an addition rather than something needed to rescue it.
Smokehouse BBQ Sauce follows that philosophy.
Crushed tomatoes provide the foundation while slowly cooked onion and fresh garlic build savory depth. Apple cider vinegar brings the tang, unsweetened apple juice adds subtle fruit sweetness, and brown monk fruit provides the brown-sugar character expected from barbecue sauce without loading the batch with conventional sugar.
Firehouse Seasoning, smoked paprika, cayenne, and dry mustard finish the flavor profile with smoke, warmth, and just enough heat.
Leave it rustic or blend it smooth.
Either way, it has one job:
Make good barbecue even better.
Recipe at a Glance
Yield: Approximately 3½–4 cups, depending on reduction
Serving Size: 2 Tbsp
Servings: Approximately 28–32
Prep Time: 15 minutes
Cook Time: Approximately 45–60 minutes
Ingredients
1 Tbsp avocado oil
200 g yellow onion, finely diced
20 g fresh garlic, minced
1 can (28 oz / 794 g) crushed tomatoes
⅓ cup apple cider vinegar
⅓ cup unsweetened apple juice
2 Tbsp Worcestershire sauce
¼ cup brown monk fruit sweetener, plus more to taste
1 Tbsp dark unsulphured molasses, optional
¾ tsp chipotle powder
½ tsp smoked paprika
1 Tbsp Firehouse Seasoning
1½ tsp dry mustard
1 tsp coarse-ground black pepper
Instructions
1. Build the Flavor
Heat the avocado oil in a medium-to-large saucepan over medium heat.
Add the 200 g finely diced yellow onion.
Cook for approximately 8–10 minutes, stirring occasionally, until the onion is completely softened and beginning to develop some golden color.
Add the 20 g minced garlic.
Cook for another 30–60 seconds, stirring frequently, just until fragrant.
Don't allow the garlic to burn.
Kirby Rule: Without tomato paste doing the heavy lifting, properly cooked onion becomes an important part of the sauce's depth. Give it time.
2. Build the Sauce
Add the entire 28-ounce can of crushed tomatoes.
Stir in:
Apple cider vinegar
Unsweetened apple juice
Worcestershire sauce
Brown monk fruit sweetener
Dark unsulphured molasses, if using
Firehouse Seasoning
¾ tsp chipotle powder
Dry mustard
Black pepper
Smoked Paprika
Stir thoroughly until everything is evenly combined.
3. Simmer & Reduce
Bring the sauce to a gentle simmer.
Reduce the heat to low.
Cook uncovered for approximately 45–60 minutes, stirring occasionally.
As the sauce cooks, the crushed tomatoes will reduce, the onion will continue to break down, and the flavors will become more concentrated.
Stir more frequently toward the end of cooking as the sauce thickens.
Continue reducing until it reaches your preferred barbecue sauce consistency.
Kirby Kitchen Tip: There's no tomato paste doing the thickening here. Time does the job instead. Let the tomatoes reduce naturally and remember that the sauce will thicken even more after cooling.
4. Taste & Adjust
Once the sauce has reduced, taste it.
For more sweetness, add additional brown monk fruit sweetener.
For more tang, add a small splash of apple cider vinegar.
For more heat, add cayenne pepper a pinch at a time.
For more smoke, add a little additional smoked paprika.
For a deeper brown-sugar and molasses character, add the optional dark unsulphured molasses or increase it slightly.
If the sauce has become too concentrated, loosen it with a small splash of water or unsweetened apple juice.
Make your final adjustments after reducing. The flavor at the beginning of the cook won't represent the finished sauce.
5. Choose Your Texture
Rustic Smokehouse
Leave the sauce as-is.
The softened onion, garlic, and crushed tomatoes give the sauce a rustic texture.
Smooth Smokehouse
Remove the saucepan from the heat and allow the sauce to cool slightly.
Carefully blend with an immersion blender until smooth.
For an especially smooth table sauce or a sauce you'll use in a squeeze bottle, blend until no noticeable pieces of onion or tomato remain.
6. Cool & Store
Allow the sauce to cool completely.
Transfer to clean airtight containers or squeeze bottles.
Refrigerate until ready to use.
The sauce will continue to thicken slightly as it chills.
Performance Notes
🍅 Start With the Whole Can
The recipe is built around an entire 28-ounce can of crushed tomatoes.
There's no half-used can left in the refrigerator, and there's no need for tomato sauce or tomato paste.
The tomatoes develop their concentration naturally as the sauce reduces.
🧅 Build Flavor With Real Aromatics
Fresh yellow onion and garlic provide the savory foundation.
Cooking the onion until soft and lightly golden develops natural sweetness and another layer of flavor underneath the tomatoes.
Using measured weights also makes the sauce easier to reproduce from one batch to the next.
🍎 Apple Works Both Sides
Unsweetened apple juice contributes subtle fruit sweetness while apple cider vinegar provides acidity.
That sweet-and-tangy combination works particularly well with smoked pork and chicken.
🍯 Brown Monk Fruit Does the Heavy Lifting
Brown monk fruit sweetener provides the deeper sweetness associated with brown sugar while keeping conventional sugar considerably lower.
For more depth, dark unsulphured molasses can be added.
The molasses is optional, so the sauce can be adjusted depending on the barbecue it's being paired with.
🔥 Smoke Without Chipotle or Liquid Smoke
Smoked paprika provides the smoky character while a small amount of cayenne brings the heat.
Using 2½ teaspoons smoked paprika + ¼ teaspoon cayenne gives us the two things chipotle powder would normally contribute without requiring another specialty spice.
And when this sauce goes onto meat that's already been properly smoked, the smoker provides the rest.
🌶️ Firehouse in the Background
Firehouse Seasoning brings additional garlic, pepper, paprika, jalapeño, and seasoning into the sauce.
It's there to support the barbecue flavor rather than dominate it.
Put It to Work
Smokehouse BBQ Sauce works especially well with:
Pulled pork
Pork ribs
Smoked chicken
Grilled chicken
Brisket
Burgers
Wings
Meatloaf

It's also the homemade BBQ sauce used as the base for Firehouse BBQ Chicken & Bacon Pizza.
