About Onions in Red Sauce for Hot Dogs

While this topping is especially popular on hot dogs, it dances well atop bratwursts, Italian sausages, burgers, and even grilled chicken or steak sandwiches.

- It is sometimes referred to as “Sabrett-style onion sauce,” named after a famous purveyor of hot dogs.

The foundation of this recipe is everyday ingredients that create a harmonious blend of flavors. Here is a breakdown of the classic elements and their roles in the dish.

| Vegetable oil | 2 tbsp | For sautéing onions |
| Tomato paste | 2 tbsp | Base for the red sauce, adds tangy richness |

Step-By-Step Preparation
Making onions in red sauce is straightforward and requires minimal cooking expertise. The following steps ensure tender onions and a flavorful, vibrant sauce every time.
- Slice and Sauté the Onions:
- Heat vegetable oil in a wide, heavy-bottomed skillet over medium heat.
- Add thinly sliced onions. Stir and cook until soft, about 10 minutes, taking care not to brown them.
- Add the Seasonings:
- Sprinkle salt, paprika, and optional sugar over the onions.
- Stir until well combined.
- Incorporate Tomato Paste and Water:
- Add tomato paste to the onions, mixing thoroughly.
- Gradually pour in water to achieve your preferred sauce consistency (start with 1/2 cup).
- Add Final Touches:
- Mix in a pinch of cayenne pepper for heat and one teaspoon of white vinegar for a touch of acidity.
- Simmer gently on low heat for 10-15 minutes, stirring occasionally until the onions are utterly tender and coated in glossy red sauce.
- Taste and Adjust:
- Check seasoning and add more salt, vinegar, or sugar to your taste.
- If the sauce thickens too much, add a splash more water.
- Serve Warm:
- Spoon generously over grilled or boiled hot dogs, sausages, burgers, or your favorite sandwich.
Chef’s Tips for Success
- Onion Choice: Yellow onions offer a milder sweetness, while red onions yield a more robust flavor and deeper color.
- Low and Slow Cooking: Avoid browning onions for best results. Gentle cooking ensures softness and a subtle, sweet finish.
- Consistency Control: Adjust water gradually; you want a spoonable sauce, not a soup. The sauce should cling to the onions.
- Flavor Balancing: Taste as you go. A pinch of sugar helps mellow acidity, but don’t overpower the savory notes with too much sweetness.
- Handling Heat: Cayenne pepper gives mild warmth. For spicier sauce, add more; for a mild sauce, omit completely.
