45 Sauce Recipe: Big Green Egg’s Signature Blend for Grilling

This signature sauce brings professional-grade flavor to any backyard grill. Developed for the Big Green Egg, it delivers the perfect balance of tangy, sweet, and smoky notes that elevate meats and vegetables alike.

With just a few simple ingredients and 10 minutes of prep, you’ll have a versatile blend that transforms ordinary dishes into restaurant-quality results. Store it in the fridge for up to 2 weeks.

Ingredients for 45 Sauce

Ten ingredients transform into this bold signature sauce for grilling perfection.

The ketchup base matters here—Heinz or Hunt’s deliver consistent results, but avoid generic brands with excessive sweetness. Apple cider vinegar should be raw and unfiltered for depth (Bragg’s is a reliable choice). For the Worcestershire, Annie’s offers an anchovy-free version if you’re avoiding fish. Liquid smoke brands vary—Colgin hickory is the standard for professional pits.

No apple cider vinegar? White vinegar with a splash of apple juice works in a pinch. Swap Worcestershire for coconut aminos at half the amount for a gluten-free option. Brown sugar can be coconut sugar, though the molasses notes will differ slightly. For heat adjustments, reduce cayenne to a quarter teaspoon or omit entirely for a milder profile.

This sauce keeps beautifully in the fridge for up to 2 weeks in a sealed container. For longer storage, freeze in ice cube trays—thaw only what you need. Always stir before using, as spices may settle over time.

Step-by-Step Instructions for 45 Sauce

This straightforward method ensures a balanced, smoky-sweet sauce perfect for grilling applications.

Step 1: Combine the Liquid Base Ingredients

In a medium saucepan, combine the 2 cups Ketchup, 0.5 cup Apple Cider Vinegar, and 0.25 cup Worcestershire Sauce. Stir thoroughly until the mixture is uniform in color and texture. The vinegar will slightly thin the ketchup initially, but this creates the ideal consistency for subsequent ingredients.

Place the saucepan over medium heat and allow the mixture to come to a gentle simmer. You’ll notice the raw vinegar aroma mellowing as it heats—this indicates the flavors are beginning to marry. Don’t let it boil vigorously, as this could cause splattering or uneven cooking.

Step 2: Add the Sweetener and Smoky Elements

Once simmering, add the 0.5 cup Brown Sugar and 2 tbsp Liquid Smoke. Stir constantly for 2-3 minutes until the brown sugar fully dissolves and the mixture takes on a deeper, more complex aroma. The liquid smoke will immediately infuse the sauce with that characteristic Big Green Egg smokiness.

Watch for the sauce to develop a glossy sheen and darken slightly in color. This visual change signals that the sugar has caramelized slightly, which balances the acidity from the vinegar and enhances the overall depth of flavor.

Step 3: Incorporate the Dry Seasonings

Reduce the heat to low and add the 2 tbsp Garlic Powder, 2 tbsp Onion Powder, 1 tbsp Black Pepper, 0.5 tsp Cayenne Pepper, and 1 tbsp Salt. Whisk vigorously to prevent clumping, as the dry ingredients can initially resist incorporating into the wet mixture.

Allow the sauce to simmer for an additional 5-7 minutes, stirring occasionally. You’ll notice the sauce thickening slightly as it cooks down. The spices will become more pronounced, and the overall flavor profile will round out. Taste and adjust seasoning if needed, though the original proportions are carefully balanced.

Step 4: Achieve the Final Consistency

After the seasonings have fully integrated, continue simmering for another 3-5 minutes until the sauce reaches your desired thickness. It should coat the back of a spoon but still be pourable—about the consistency of a thin barbecue sauce.

Remove the saucepan from the heat and let the sauce cool to room temperature. As it cools, it will thicken slightly more. This resting period also allows the flavors to fully meld together, resulting in a more cohesive and balanced final product.

Storing and Reheating This Recipe

Refrigerator Storage

Once cooled, transfer this sauce to a clean, airtight container—I use 16-ounce mason jars for easy pouring. It keeps beautifully in the fridge at 40°F or below for up to 2 weeks. The flavors deepen over time, making it even better after a few days. ❄️

Freezer Storage

For longer storage, pour into ice cube trays and freeze until solid. Transfer cubes to a freezer bag and store for up to 3 months. This method lets you thaw only what you need—each cube is about 2 tbsp. Squeeze out excess air to prevent freezer burn.

Thawing with Care

Move frozen sauce to the fridge overnight for gradual thawing. For quick use, place the container in a bowl of cold water, changing water every 30 minutes. Never thaw at room temperature, as this can promote bacterial growth.

Reheating Methods

Gently warm on the stovetop over low heat in a small saucepan, stirring frequently. Add 1-2 tbsp water if it thickens too much. Avoid boiling, which can make the sauce too thin and alter the flavor balance.

Room Temperature Use

If using straight from the fridge, let it sit at room temperature for 20-30 minutes before serving. Cold sauce won’t cling as well to grilled meats. Always stir well, as spices may settle during storage.
