The beef gives up a little of its browned crust when the broth goes into the pot, and those dark bits dissolve into the chili instead of getting left behind. That’s the part I watch for when making Texas chili with cubed sirloin and cumin: the bottom of the Dutch oven should smell savory, not scorched. Browning the meat in batches takes an extra few minutes, but it gives the broth a deeper start than adding all the beef at once.
Sirloin keeps each bite meaty and distinct, while cumin brings a warm, earthy note through the broth. I finish the pot with a smooth masa harina slurry rather than relying on a long, uncovered reduction to thicken it. The result is a hearty chili with tender beef and a broth that clings to the cubes without turning pasty.
Kitchen Note
Give the beef room when it browns. Crowded cubes release moisture and steam before they can develop the dark edges that build the chili’s savory base.
Save this Texas chili with cubed sirloin and cumin for a slow-simmered pot with tender beef and a rich, masa-thickened broth.
Why the Masa Thickener Goes In After the Beef Is Tender
Masa harina does more than make the chili thicker. It gives the broth a gentle corn character and helps it coat the sirloin, but it needs a little time to hydrate before the final texture settles. Adding it near the end means the beef can braise in a thinner broth for the full tenderizing stretch instead of simmering in a thick mixture that’s more likely to catch on the bottom.
Whisking the masa harina with water first matters, too. Dry masa stirred straight into a pot tends to form little pockets that are hard to smooth out once they’re surrounded by hot broth. A smooth slurry disperses evenly, and the short uncovered simmer gives it time to thicken the liquid without reducing the chili down too far. If you prefer a looser bowl, stop cooking when the broth lightly coats a spoon rather than waiting for it to look dense.
This approach keeps the beef at the center of the dish. The broth becomes substantial enough to cling to the cubes, while the pieces stay intact instead of disappearing into a thick, uniform stew.
What Sirloin, Cumin, and Masa Each Bring to the Pot
- Sirloin — The 1 1/4-inch cubes give this chili its substantial, beef-forward texture. Ask for a cleanly trimmed piece and cut the cubes evenly so they braise at a similar pace. Stew meat can be a mix of cuts and sizes, so it won’t be as predictable at the same cooking time.
- Ground cumin — Cumin provides the earthy aroma that defines the pot. A fresh jar smells warm and fragrant as soon as it hits the hot spices; if yours has been open for years and smells faint, the finished chili will taste flatter. Ground cumin is the right texture for blending into the broth here.
- Chili powder — This is the main dried-chile seasoning, not a last-minute garnish. Use the chili powder you enjoy in cooked dishes; the quality of the blend matters more than buying an expensive brand. Keep it with the cumin and oregano for the brief bloom in the pot.
- Masa harina — This finely ground corn flour thickens the broth and adds a subtle corn note that all-purpose flour won’t provide. Keep it dry and fresh, then whisk it with water until no dry pockets remain. Fine cornmeal is not an exact stand-in; it tends to leave a coarser texture.
- Low-sodium beef broth — It supplies the liquid for the long covered simmer and lets the salt level stay more controlled. A flavorful, everyday carton works well; a premium broth isn’t necessary when the beef, onion, and spices have time to enrich it.
- Yellow onion, garlic, and oregano — These form the savory base around the beef and cumin. A firm onion and fresh garlic are worth choosing because they carry the first layer of flavor, while dried oregano is perfectly suited to this long simmer.
How to Brown, Braise, and Thicken the Sirloin
Build a Dark Crust in Batches
Pat the sirloin dry, season it evenly with kosher salt and black pepper, and heat the oil in a 5- to 6-quart Dutch oven over medium-high heat until shimmering. Brown the beef in three batches, adding oil before each batch, then transfer each batch to a plate. Leave space between the cubes so they sear rather than steam. The goal is browned edges; the centers will finish cooking during the braise.
Soften the Onion and Bloom the Spices
Add the diced onion and cook over medium heat for 5 to 7 minutes, stirring while you scrape up the browned bits from the pot. The onion should soften and turn glossy without taking on dark, burned spots. Stir in the garlic, chili powder, cumin, and oregano, and cook for 30 seconds until fragrant. Keep stirring during this short step so the garlic and spices don’t scorch.
Let the Beef Braise Until Fork-Tender
Pour in the beef broth and scrape the bottom of the pot again, then return the browned beef and any juices on the plate. Bring the chili to a gentle simmer, cover the Dutch oven, and cook over low heat for 1 1/2 to 2 hours, stirring occasionally. Keep the heat low enough that the liquid bubbles gently rather than boiling hard. The beef is ready when a fork pierces a cube easily and it has reached at least 145°F.
Stir in the Slurry and Let the Pot Rest
Whisk the masa harina with the water in a small bowl until smooth, then stir it into the chili. Simmer uncovered over low heat for 10 to 15 minutes, stirring occasionally as the broth thickens. If the bottom begins to catch, lower the heat and scrape as you stir. Take the pot off the heat and let it rest for 10 minutes before serving.
Three Practical Ways to Adapt This Chili
Swap in beef chuck for a richer braise
Use evenly cut chuck cubes in place of sirloin when you want a richer, more succulent texture. Chuck may need longer in the covered simmer than sirloin, so use fork tenderness—not the clock alone—as your cue to move on to the masa slurry.
Make the cumin less prominent
For a milder cumin note, reduce the ground cumin to 1 1/2 teaspoons. The chili will still have warmth from the chili powder and oregano, but it won’t have quite the same earthy finish as the full tablespoon.
Keep it gluten-free
Masa harina is made from corn, so it thickens the chili without wheat flour. If you’re cooking for someone who must avoid gluten, choose masa harina produced and packaged to prevent cross-contact; the texture and corn flavor stay true to the dish.
Storage and Reheating
- Refrigerator: Store in a covered container for 3 to 4 days. The masa-thickened broth may firm up as it chills.
- Freezer: Freeze in airtight, freezer-safe portions for up to 3 months. Thaw overnight in the refrigerator for more even reheating.
- Reheating: Warm gently in a covered saucepan over low heat, stirring now and then, until it reaches 165°F. Avoid a hard boil, which can make the beef feel tougher and cause the thickened broth to catch.
