Method
Step-by-Step
- Heat the oil in a medium saucepan over medium heat. Whisk in the flour and cook for about 1 minute, stirring constantly, until a light roux forms.
- Add the chili powder, cumin, garlic powder, onion powder, oregano, and optional cayenne. Whisk for about 30 seconds, just until fragrant.
- Gradually pour in the broth while whisking continuously. Add it in a slow stream so the flour disperses smoothly without forming lumps.
- Stir in the tomato sauce and kosher salt. Bring the mixture to a gentle simmer rather than a vigorous boil.
- Cook for 10–15 minutes, whisking occasionally, until the sauce is smooth and slightly thickened. Taste and adjust the salt or heat before using.
Notes
The sauce should lightly coat a spoon while remaining pourable, and it thickens a little more as it cools. Refrigerate in an airtight container for up to 5 days or freeze for approximately 2–3 months. If it is too thick after reheating, whisk in a little broth.
