Storage Tips
Store any leftover sweet peppers in an airtight container in the refrigerator for up to 5 days.
To reheat, just place them in a skillet on low heat until they are heated through. They can also be stored in freezer-safe bags and kept in the freezer for as long as 2 months.
Why This Recipe Works So Well
The combination of sautéing and simmering allows the peppers to soften slowly and absorb all the seasonings.
This technique makes them tender, flavorful, and similar to Portillo’s version. The sweetness from sugar and the tang from vinegar create a delicious balance.
Common Mistakes to Avoid
Don’t cook the peppers on high heat, as they may burn instead of caramelizing. Avoid over-seasoning, since the flavor deepens naturally during simmering.
Using too little oil or skipping vinegar also prevents the peppers from achieving the right taste and texture.
How to Customize This Recipe
You can easily make this Portillo’s Sweet Peppers Recipe your own. Add crushed red pepper flakes for a hint of heat, or toss in onions for a sweeter base.
You can even use roasted garlic instead of fresh to bring a deeper, mellow flavor.
