Monterrey-style chili dogs—often called Chili Dogs Regios—are a legendary street food favorite from where I grew up: Nuevo León, Mexico. Unlike a traditional American chili dog where an all-meat chili sauce is ladled over a whole hot dog, the undeniable style of the chili dog from Monterrey is that the chili is made as a rich, savory guiso (stew) made of chopped hot dogs, smoky Mexican chorizo, ground beef, and pinto beans all simmered together in a tangy tomato-ketchup base.
It is a high-yield, budget-friendly dish traditionally served at kid’s birthday parties (piñatas) and family gatherings. It delivers a perfectly thick, smoky, and slightly sweet filling loaded into warm, soft bread.
Why This Recipe Works
- One-Pot Filling: The meat, sausage, and beans are all cooked together in a single stock pot, allowing the flavors to fuse completely.
- Thick & Scoopable: The starch from slightly mashed pinto beans naturally thickens the sauce, ensuring the filling stays inside the bun without making it soggy.
- Authentic Flavor Profile: The signature mix of savory pork chorizo, ground beef, tomato purée, ketchup, and a splash of jalapeño vinegar creates that unmistakable Regio flavor. I dare you to eat only one of these chili dogs!
Ingredients You'll Need
Ground Beef (90/10 or 80/20 lean): This provides the hearty, rich base for the meat sauce. The slight fat content helps carry the spices throughout the dish.
Mexican Chorizo: The ultimate flavor bomb. As it renders down, it releases deep smoky notes.
Beef Hot Dogs: The signature element of a Monterrey-style dog. Slicing them up allows them to simmer directly in the sauce, absorbing the juices so that every single spoonful has hot dog in it.
Cooked Pinto Beans (or Ranch Style Beans): These add an authentic, creamy texture and stretch the meal perfectly.
White Onion (finely diced): Sautéed early on to create a sweet, sharp foundational layer of flavor.
Garlic (minced): Adds a sharp, essential savory aroma that cuts through the heavy meats.
Tomato Purée: Provides the smooth, saucy body that binds the meats and beans together without thinning out the flavor.
Ketchup: Non-negotiable for true Chili Dogs Regios. It delivers the traditional, nostalgic hint of sweetness to street-style chili dogs.
Yellow Mustard: Adds a sharp, hidden punch of acidity.
Pickled Jalapeño Vinegar: The secret street-food weapon. Taking this straight from the canned jalapeño jar injects a spicy tang that brightens the whole pot.
Herbs and Spiced (Oregano, Onion Powder, Garlic Powder, Paprika, Cumin) Adds a distinct herbal note and enhances the flavor.
How to Make Monterrey-Style Chili Dogs
1. Brown and Season the Meats
Heat a large, deep skillet over medium-high heat. Add the pork chorizo, breaking it apart with a wooden spoon. Cook for 3–4 minutes until it begins to render its fat.
Add the ground beef, diced onion, and minced garlic along with your herbs and spices (oregano, onion powder, garlic powder, cumin, and paprika) to the skillet. Cook until the beef is fully browned, draining any excess grease if desired.
2. Fry the Hot Dogs
Slice the hot dogs into half moons. Stir the sliced hot dog directly into the meat mixture. Sauté for another 4–5 minutes until the edges of the hot dog pieces begin to brown and crisp up slightly.
3. Build the Chili Base
Turn the heat down to medium-low. Pour in the tomato purée, ketchup, yellow mustard, and black pepper. Stir thoroughly to coat all the meats evenly.
4. Add the Secret Ingredient: Beans
Incorporate the pinto beans along with 1/4 cup of the bean broth. Using the back of your spoon or a potato masher, gently press down on about half of the beans. Smashing them releases starch, turning the mixture into a thick, uniform, scoopable chili guiso.
5. Simmer and Finish
Stir in the pickled jalapeño vinegar. Let the mixture simmer on low for 8–10 minutes, stirring occasionally, until it thickens into a rich, luscious sauce. Taste and adjust with a pinch of salt if necessary.
6. Assemble and Serve
Slice open your hot dog buns or fresh bolillos. If desired, lightly toast them on a comal or griddle. Generously ladle the hot Monterrey-style chili filling directly into the buns.
Pro Tip
The Mandatory Garnish: In Monterrey, these are never served alone. You must serve them with a side of classic potato chips (like Ruffles or Sabritas) and pickled jalapeños. Many people even crush the potato chips directly on top of the chili dog for an incredible crunch.
How to Store and Reheat Monterrey Style Chili Dogs
Storing
Because this recipe makes a rich, flavorful guiso (stew), it actually tastes even better the next day as the flavors continue to meld together!
In the Refrigerator (Short-Term)
- Cool it down: Allow the guiso to cool completely to room temperature before storing. Leaving hot sauce in a sealed container can create condensation, which thins out the flavor.
- Container: Transfer the mixture to an airtight glass or plastic container.
- Shelf Life: Store it in the fridge for up to 3 to 4 days.
- Freeze the sauce only: Only freeze the meat and bean guiso mixture. Do not freeze the buns or bolillos, as they will become soggy and ruin upon thawing.
- Container: Use a heavy-duty freezer-safe bag (press out excess air to prevent freezer burn) or a rigid, airtight freezer container. Leave about a half-inch of space at the top, as the liquid will expand slightly when frozen.
- Shelf Life: It will keep beautifully in the freezer for up to 3 months.
- Thawing: For best results, transfer the frozen container to the refrigerator the night before you plan to eat it to let it thaw safely.
How to Reheat
- Stovetop (Recommended): Place the guiso in a saucepan over medium-low heat. Add a splash of water, beef broth, or tomato juice if the mixture has thickened up too much in the fridge. Stir frequently until heated through.
- Microwave: Place a portion in a microwave-safe bowl and cover it with a paper towel (it will splatter!). Microwave on high in 45-second intervals, stirring in between, until steaming hot.
Make It Ahead: This chili tastes even better the next day once the smoky chorizo oils fully infuse into the pinto beans. It reheats beautifully on the stovetop with a splash of water or extra bean broth.
Party Style: If you’re feeding a crowd, keep the chili filling warm in a slow cooker or Crockpot on the “warm” setting, allowing guests to build their own chili dogs regios.
