Equipment

• 1 Airtight Container/ Ziplock bag
• 1 Baking sheet
• 1 Freezer
• 1 knife

Instructions

• Choose Fresh, Firm Poblano Peppers

  The first step is to select fresh poblano peppers without any bruises, soft spots, or signs of spoilage. Look for peppers that are brightly colored and firm to the touch. Avoid peppers with shriveled skin or brown spots. For the best results, buy poblano peppers in season during the late summer and early fall harvest months. You can often find fresh poblano peppers at your local grocery store, farmers market, or Latin market.
  
• Wash and Dry the Peppers

  Rinse the poblano peppers under cold water to remove any dirt or debris. Use a paper towel or clean kitchen towel to pat them dry gently. Ensure no excess moisture is left outside the peppers before freezing. Any water left on the surface could cause ice crystals to form during freezing, damaging the peppers.

  Roast the Poblanos 

  (Optional)

  For extra flavor, consider roasting the poblano peppers before freezing. To roast, place the peppers directly over an open flame on your gas stove or grill. Use tongs to turn the peppers until the skin is evenly charred and blistered on all sides. This usually takes 1-2 minutes per side. You can also roast poblano peppers under the broiler in your oven or over a hot grill. Roasting helps remove the waxy skin and brings out the sweet, smoky flavor.

  After roasting, place the peppers in a bowl and cover with plastic wrap or a plate. Let them steam for 10-15 minutes. The skin will easily peel off. Remove skins, stems, and seeds before freezing.
  
• Prepare the Peppers for Freezing

  Poblano peppers can be frozen whole or sliced into pieces. To freeze whole, leave stems intact and wash and dry the peppers before freezing. Remove stems and seeds, then slice peppers into strips or dice into pieces.

  Small slices or diced peppers will be easier to use later in recipes. But leaving peppers whole requires less prep work upfront. Either way works great, so please choose the best method for using the peppers.

  Arrange on Baking Sheet in Single Layer

  Line a baking sheet with parchment paper or wax paper. Arrange peppers on the sheet in a single layer, ensuring they are not touching or overlapping. Freezing peppers in a single layer prevents them from freezing together in a large clump, so you can easily remove only what you need later.
  
• Freeze First

  Place the baking sheet with pepper slices or whole peppers in the freezer. Allow them to freeze completely solid, which takes 1-2 hours. Freezing the peppers before storing them makes them easier to handle without bruising or damage.

  Transfer to an Airtight Container or Bags

  Once fully frozen, transfer the poblano peppers to an airtight container or freezer bag. Heavy-duty ziplock freezer bags work well for storing sliced peppers. Wide-mouth glass jars or rigid plastic freezer containers are suitable for whole peppers.

  Press out any excess air and seal the containers or bags tightly. Be sure to label the containers with the contents and freeze date. Properly sealing and labeling your frozen poblanos reduces freezer burn and makes contents easy to identify later.
