The Story Behind French Onion Soup
French onion soup has a rich history that dates back to ancient Rome, but it became a staple in French cuisine during the 18th century. Traditionally, it features caramelized onions simmered in a savory broth, topped with melted cheese and crusty bread. Its warm, hearty nature makes it perfect for chilly evenings, and by canning it, you can bring a piece of this culinary tradition into your home anytime!
Ingredients You'll Need
Before diving into the canning process, gather the following ingredients:
- 3 lbs of onions (yellow or sweet)
- 4 cloves of garlic, minced
- 8 cups of beef or vegetable broth (preferably homemade)
- 1 cup of dry white wine (optional, but recommended)
- 1 tablespoon of balsamic vinegar
- 1 tablespoon of olive oil
- 2 teaspoons of salt
- 1 teaspoon of black pepper
- 1 tablespoon of fresh thyme or 1 teaspoon of dried thyme
- 1 tablespoon of sugar (to enhance caramelization)
- Canning jars with lids and rings (quart-size is ideal)
Preparation Tips: Getting Started
1. Slice Your Onions
Start by slicing your onions thinly. The key to great French onion soup is the caramelization process, which requires patience. Aim for uniform thickness to ensure even cooking. If you have a mandoline slicer, it can save you time and give you consistent slices.
2. Caramelize the Onions
In a large pot, heat the olive oil over medium heat. Add the sliced onions and sugar, stirring frequently. This process can take about 30-40 minutes. You want the onions to turn a deep golden brown without burning. The secret is to keep the heat steady and low, allowing the sugars in the onions to develop their rich flavors.
3. Add Garlic and Deglaze
Once your onions are beautifully caramelized, add the minced garlic and cook for another minute. Then, deglaze the pot by adding the wine (if using) and scraping up any brown bits at the bottom. This step adds depth to your soup!
4. Add Broth and Seasonings
Next, pour in the beef or vegetable broth, balsamic vinegar, thyme, salt, and pepper. Bring the mixture to a gentle boil, then reduce the heat and let it simmer for 30 minutes. This allows all the flavors to meld beautifully.
Canning Techniques: A Step-by-Step Guide
1. Prepare Your Jars
Sterilize your canning jars and lids in boiling water or a dishwasher. This is a crucial step to prevent bacteria growth. Let them air dry while you finish the soup.
2. Fill the Jars
Using a ladle, carefully fill your sterilized jars with the hot French onion soup, leaving about an inch of headspace at the top. This ensures a good seal.
3. Remove Air Bubbles
Run a non-metallic spatula around the inside of the jar to release any trapped air bubbles. Wipe the rims of the jars with a clean cloth to remove any food residue.
4. Seal and Process
Place the lids on the jars and screw the rings on until they are finger-tight. Process the jars in a boiling water bath for 25-30 minutes (adjust time based on your altitude). Ensure the jars are fully submerged in water during processing.
5. Cool and Store
Once processed, carefully remove the jars and let them cool on a clean kitchen towel or cooling rack. You should hear a satisfying "pop" as the jars seal. Once completely cooled, check the seals by pressing down in the center of the lid—if it doesn’t pop back, it’s sealed!
