The beef broth is the foundation—low-sodium lets you control the seasoning. Swanson or College Inn are reliable grocery store options. For deeper flavor, Better Than Bouillon beef base mixed with hot water works beautifully (just reduce the soy sauce by half). Unsalted butter is non-negotiable here; salted can make the final gravy too salty once reduced.

No Worcestershire? Soy sauce plus a splash of lemon juice gets you close. Cornstarch is the thickener of choice—arrowroot at the same ratio works if that’s what you have. For a gluten-free option, swap the all-purpose flour for rice flour or cornstarch (use 1.5 tbsp for the same thickening power). The garlic and onion powders are subtle but essential for that classic loco moco flavor.

This gravy keeps 4-5 days in the fridge, though it thickens as it cools—just warm with a splash of water. Freezes for up to 3 months. Make a double batch and freeze in ice cube trays for quick portioning.

Step-by-Step Instructions for Loco Moco Gravy

This straightforward method delivers a velvety, flavor-packed gravy that elevates your dish effortlessly.

Step 1: Create a Rich Roux Base

Melt the 2 tbsp Unsalted Butter in a medium saucepan over medium heat. Once foaming subsides, add the 2 tbsp All-Purpose Flour and whisk constantly for 1-2 minutes until the mixture turns a light golden color and emits a nutty aroma.

This router step is critical—it removes the raw flour taste and builds the foundation for your gravy’s body. Keep the heat moderate to avoid burning, which would impart a bitter flavor. The mixture should resemble wet sand when ready.

Step 2: Build Flavor with Broth and Seasonings

Slowly pour in the 2 cups Beef Broth while whisking vigorously to prevent lumps from forming. Add the 1 tbsp Worcestershire Sauce, 1 tbsp Soy Sauce, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, and 0.5 tsp Black Pepper.

Increase heat to medium-high and bring to a gentle boil. The soy and Worcestershire will deepen the color to a rich mahogany while adding layers of umami. Reduce heat to maintain a steady simmer, cooking for 3-4 minutes to allow flavors to meld.

Step 3: Thicken to Perfect Consistency

In a small bowl, whisk together the 2 tbsp Cornstarch and 0.25 cup Cold Water until completely smooth. This slurry will thicken your gravy without creating lumps that dry cornstarch might.

While whisking constantly, slowly pour the slurry into the simmering gravy. Continue whisking for 1-2 minutes until the mixture thickens to coat the back of a spoon. The gravy should flow like heavy cream—not too thin, not glue-like. If it thickens too much, whisk in a splash of water.

Step 4: Finish and Serve

Reduce heat to low and let the gravy simmer for an additional 2-3 minutes. This final cooking time allows the flavors to fully develop and the thickness to stabilize. Taste and adjust seasoning if needed, though the soy sauce typically provides sufficient saltiness.

Remove from heat and use immediately. The gravy will thicken slightly as it cools, so serve it warm over your loco moco components. For the smoothest texture, strain through a fine-mesh sieve if any lumps formed during cooking.

Dietary Considerations for This loco moco gravy recipe easy

Keto-Friendly Options

For a keto-friendly loco moco gravy, replace all-purpose flour with almond or coconut flour to thicken the sauce. Use a sugar-free beef or mushroom broth to keep carbs low, and opt for grass-fed butter or ghee instead of vegetable oils for healthier fats. A splash of coconut aminos can add umami without the sugar.

Gluten-Free

To make this gravy gluten-free, swap regular soy sauce for tamari or coconut aminos, and use a gluten-free thickener like cornstarch or arrowroot powder. Always check broth labels to ensure they’re certified gluten-free, as some brands contain hidden wheat.

Allergens

This recipe commonly includes dairy (butter) and wheat (flour). For dairy-free versions, use coconut oil or olive oil. For nut allergies, avoid almond flour and stick to cornstarch or rice flour. If soy is a concern, omit soy sauce or use a soy-free alternative like coconut aminos.

Vegetarian Modifications

For a vegetarian loco moco gravy, replace beef broth with mushroom or vegetable broth and use mushroom-based umami boosters like miso paste or nutritional yeast. Swap beef drippings for olive oil or vegan butter to maintain richness.

Low-Sodium

To reduce sodium, use low-sodium or homemade broth and limit added salt. Boost flavor with fresh herbs, garlic, and black pepper instead. If using soy sauce, opt for a reduced-sodium version or dilute it with a splash of water.
