About this recipe

Portillo's sweet peppers are a delightful addition to many of their iconic dishes, such as Chicago-style hot dogs and Italian beef sandwiches.

These sweet peppers add a burst of tangy and slightly sweet flavor that perfectly complements the savory and meaty components of these dishes.

The sweet peppers used at Portillo's are typically a combination of red, green, and yellow bell peppers. The peppers are thinly sliced into long strips, creating a vibrant and colorful medley. This variety of peppers not only adds visual appeal but also contributes to the complexity of flavors.

To prepare Portillo's sweet peppers, the sliced peppers are sautéed along with thinly sliced onions and minced garlic.

This step helps to soften the peppers and onions, releasing their natural sweetness and infusing the dish with delicious aromas. The combination of peppers, onions, and garlic creates a flavorful base for the sweet peppers.

Next, a mixture of red wine vinegar, granulated sugar, dried oregano, crushed red pepper flakes, salt, and pepper is added to the skillet. This tangy-sweet marinade further enhances the taste of the peppers, balancing their natural sweetness with a subtle tanginess and hint of spiciness from the red pepper flakes.

The sugar in the marinade helps to caramelize the peppers slightly, adding a delightful caramelized flavor to the dish.

Once the peppers have absorbed the flavors of the marinade, they are transferred to a baking dish and cooked in the oven. Baking the peppers allows them to further soften and develop a slightly charred and caramelized exterior. This step adds depth and richness to the overall taste of the sweet peppers.

The end result is a medley of tender, slightly caramelized sweet peppers with a perfect balance of tangy and sweet flavors. These peppers not only add a pop of color to dishes but also bring a burst of flavor that complements and enhances the other components of the meal.

Whether enjoyed on a hot dog, sandwich, or as a side dish, Portillo's sweet peppers are a delicious and iconic element of their cuisine.

Potential ingredients substitutes

  • Bell Peppers: If you don't have or prefer not to use bell peppers, you can substitute them with other sweet peppers like Cubanelle peppers, banana peppers, or even sweet mini peppers. These peppers will still provide a sweet and vibrant flavor to the dish.
  • Onions: If you're not a fan of onions or don't have them on hand, you can omit them from the recipe. However, keep in mind that the onions add depth of flavor and sweetness to the sweet peppers. If you'd like a similar flavor, you can try substituting with shallots or leeks, thinly sliced and sautéed.
  • Garlic: If you don't have garlic or prefer not to use it, you can omit it from the recipe. The garlic adds a savory note to the dish, but the sweet peppers will still be flavorful without it.
  • Red Wine Vinegar: If you don't have red wine vinegar, you can substitute it with other types of vinegar, such as apple cider vinegar or white wine vinegar. The tanginess and acidity of these vinegars will provide a similar effect in balancing the sweetness of the peppers.
  • Granulated Sugar: Granulated sugar adds sweetness and helps caramelize the peppers slightly. If you prefer to reduce or avoid sugar, you can substitute it with honey, maple syrup, or a natural sweetener of your choice. Adjust the amount according to your taste preference.
  • Dried Oregano: If you don't have dried oregano, you can substitute it with dried basil, dried thyme, or Italian seasoning. These herbs will provide a complementary flavor to the sweet peppers.
  • Crushed Red Pepper Flakes: If you prefer less spiciness or don't have crushed red pepper flakes, you can omit them from the recipe. However, if you enjoy spiciness, you can substitute with cayenne pepper or a pinch of chili powder for a milder kick.
