Instructions to Make Loco Moco Gravy
Cook the Rice:

Prepare the Hamburger Patties:
- Divide the ground beef into four equal portions and shape them into patties.
- Season both sides of each patty with salt and freshly ground black pepper.
- Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
- Add the patties to the skillet and sear for about 4 minutes on each side, or until they reach your desired level of doneness.
- Remove the patties from the skillet and set them aside.
Make the Gravy:
- Reduce the heat to medium-low.

Tips for Making the Perfect Loco Moco Gravy
- Use Quality Beef Broth: The flavor of your gravy heavily depends on the broth. Opt for a high-quality or homemade beef broth for the best results.
- Don’t Skip the Roux: Properly cooking the flour in the butter ensures your gravy is smooth and free of a raw flour taste.
- Incorporate Pan Drippings: If you’re making hamburger patties, deglaze the pan with some beef broth and add those flavorful drippings to the gravy.
- Whisk Continuously: This prevents lumps and creates a silky texture.
- Taste as You Go: Regularly taste the gravy and adjust seasonings to suit your palate.

What to Serve with Loco Moco Gravy
Loco moco gravy isn’t just for loco moco! Pair it with:
- Steamed rice: The perfect base for soaking up all the savory gravy.
- Mashed potatoes: A comforting side that complements the gravy beautifully.

Variations
The beauty of loco moco gravy lies in its versatility. While the classic version is perfect as is, there are plenty of ways to adapt it to suit your taste preferences or dietary needs. Here are some delicious variations to try:
1. Vegetarian or Vegan Loco Moco Gravy
- Vegetarian: Swap the beef broth for a hearty vegetable broth. Mushroom broth works especially well as it brings an earthy and umami-rich flavor.
- Vegan: Use plant-based butter or olive oil in place of regular butter. Substitute soy sauce with tamari for a vegan-friendly option, and ensure your Worcestershire sauce is vegan (some versions contain anchovies).
2. Spicy Loco Moco Gravy
Give your loco moco gravy a bold, spicy kick by adding a pinch of cayenne pepper, a splash of hot sauce, or a teaspoon of sambal oelek. This variation enhances the rich, savory flavors with a touch of heat, making it perfect for those who enjoy a little spice in their comfort food.
3. Mushroom Loco Moco Gravy
Add depth and texture to your gravy by sautéing sliced mushrooms and mixing them into the sauce. The mushrooms bring a hearty, earthy flavor that pairs perfectly with the rich, umami taste of traditional loco moco gravy, making this version even more satisfying.
4. Creamy Loco Moco Gravy
- For a decadent twist, stir in 1/4 cup of heavy cream or coconut milk at the end of cooking. This creates a velvety, luscious gravy that pairs exceptionally well with the hamburger patty and rice.
5. Garlic Herb Loco Moco Gravy
- Elevate your gravy by adding freshly minced garlic and chopped herbs like thyme or parsley. This variation introduces a more aromatic and sophisticated flavor profile, perfect for special occasions.
6. Pan Drippings Gravy
- Don’t let the flavorful bits from cooking your hamburger patties go to waste! After cooking the patties, deglaze the pan with a splash of beef broth and scrape up those browned bits. Use this as the base for your loco moco gravy to add a smoky and savory depth.
7. Gluten-Free Loco Moco Gravy
- For those avoiding gluten, replace the all-purpose flour with cornstarch or a gluten-free flour blend. If using cornstarch, dissolve it in water first to avoid lumps.
8. Hawaiian BBQ Gravy
- Mix a tablespoon of Hawaiian BBQ sauce into the gravy for a sweet and tangy flavor twist. This is a great option if you’re serving the loco moco as part of a Hawaiian-themed meal.
With these variations, you can customize your loco moco gravy to suit any palate or occasion while staying true to the essence of this Hawaiian classic.
Recipe Tested & Notes
I tested this Loco Moco Gravy several times with different amounts of beef drippings, butter, flour, broth, and seasonings to find the right balance of richness and thickness.
The biggest difference during testing was the consistency. A gravy that was too thick became difficult to spoon over the hamburger patty and rice, while a thin gravy did not coat the dish properly. The final version has a smooth, pourable consistency that lightly coats the back of a spoon.
I found that making a proper roux was important. Cooking the flour with the fat for a couple of minutes removed the raw flour taste and created a better foundation for the gravy.
Adding the broth gradually also made a big difference. Pouring it in slowly while whisking prevented lumps and produced a much smoother gravy.
I tested both beef broth and beef stock. Both worked, but a flavorful beef broth created a rich gravy without needing too many additional seasonings.
The hamburger drippings added another layer of flavor. When available, I preferred using some of the flavorful fat left from cooking the patties rather than relying entirely on butter.
I also found that Worcestershire sauce should be added carefully. It provides a savory depth that works beautifully with beef, but too much can overpower the gravy.
The final version is rich, savory, smooth, and flavorful enough to bring together the hamburger patty, rice, and fried egg in a classic Loco Moco.
Mistakes I Made
Testing this recipe helped me avoid several common gravy mistakes.
Adding the broth too quickly
Pouring in a large amount of broth at once made the roux harder to incorporate and created lumps. Adding the broth gradually while whisking worked much better.
Not cooking the flour
Adding flour and immediately pouring in the liquid left a noticeable raw flour flavor. Cooking the roux briefly improved the taste.
Making the gravy too thick
It is easy to over-thicken gravy while it is cooking. Remember that it will continue to thicken slightly as it cools.
Using too much seasoning
Beef broth, pan drippings, and Worcestershire sauce can all contain salt. I found it better to season gradually and taste before adding more.
Letting the gravy sit uncovered
Gravy develops a skin as it cools. Keeping it covered when resting helped maintain a smoother surface.
Personal Cooking Tips Learned From Testing
These tips consistently gave me the best results:
- Use flavorful beef drippings when available.
- Cook the flour and fat long enough to remove the raw flour taste.
- Add warm broth gradually.
- Whisk constantly while adding the liquid.
- Scrape the bottom of the pan to incorporate flavorful browned bits.
- Season gradually because the broth may already be salty.
- Add Worcestershire sauce in moderation.
- Simmer gently rather than boiling aggressively.
- Keep the gravy slightly thinner than your final desired consistency because it thickens as it cools.
- If the gravy becomes too thick, whisk in a little warm broth.
- Strain the gravy if you want an especially smooth restaurant-style texture.
Why I Prefer This Version
After testing several gravy methods, I prefer this version because it is rich and savory without being overly heavy.
Using beef drippings adds a deeper beef flavor that works especially well with the hamburger patty. The roux provides enough body to make the gravy cling to the rice without becoming thick and pasty.
I also like the balance of seasoning. The beef broth provides the main savory foundation, while Worcestershire sauce adds depth without taking over.
This gravy is also simple enough to prepare while the hamburger patties are cooking. That makes it practical for a homemade Loco Moco without requiring a complicated sauce.
Most importantly, the gravy brings all the components together. When spooned over rice and a hamburger patty and topped with a fried egg, it creates the rich, comforting combination that makes Loco Moco so satisfying.
Storage Notes Based on Actual Testing
I tested different storage and reheating methods to see how well the gravy held up.
Refrigerator
The gravy stored well in an airtight container in the refrigerator for about 3 to 4 days.
It becomes noticeably thicker when chilled, which is normal.
Stovetop Reheating
The stovetop produced the best results. Warm the gravy gently over low to medium-low heat while whisking occasionally.
If it has become too thick, add a small amount of warm beef broth or water until the desired consistency returns.
Microwave
The microwave works for smaller portions. Heat in short intervals and stir between each interval to prevent hot spots.
Freezing
This gravy can be frozen, although the texture may separate slightly after thawing. Whisking it thoroughly while reheating usually helps bring it back together.
Store in a freezer-safe container with a little room for expansion.
Make-Ahead Preparation
The gravy can be made ahead of time and refrigerated. Reheat gently before serving and adjust the consistency with a splash of broth if necessary.
