Simple French Onion Soup

Winter has made a serious appearance today. “Like a Nor-Easter, but no snow..”, they said. And I just got back from a week in a much warmer climate. It’s too cold for me; it’s time for some serious comfort food.
I’m thinking of home-cooked onion soup, rich stock, caramelized onions, crusty bread, toasty, melty cheese. The real pain is the time it takes to caramelize the onions. But perhaps a bit of technology will help me here. I’ll use my Instapot to caramelize several pounds of onions, then build my soup based on that.
From Wikipeida:
French onion soup (French: soupe à l’oignon [sup a lɔɲɔ̃]) is a soup of onions, gently fried and then cooked in meat stock or water, usually served gratinéed with croutons or a larger piece of bread covered with cheese floating on top. Onion soups were known in France since medieval times, but the version now familiar dates from the mid-19th century.
First of all, the Onions:

InstaPot Onions

Ingredients

- 1/2 tsp Black Pepper Coarse grind or smal crack
- 1 cup White Wine Dry. Sauvignon Blanc, Pinot Grigio
Instructions
- Add onions, butter, salt, and pepper to the container of an Instant Pot or other multi-use pressure cooker and stir to combine.

- Drain excess liquid from onions and return them to pot.

- Add white wine and cook down again until wine is evaporated.
- Remove from heat and store in an airtight container in the refrigerator for up to 1 week.
