Marinated mushrooms are delicious straight from the jar and make a flavorful addition to charcuterie boards, salads, pizzas, or as a versatile ingredient in many recipes.
Mushrooms can be challenging to preserve without losing texture or flavor. While there are a few reliable preserved mushroom products—such as canned soup bases—marinated mushrooms offer a distinctly different use. They retain an appealing bite and gain extra flavor from the marinade, making them ideal for Italian dishes, pizza toppings, antipasto and charcuterie plates, or tossed into fresh salads.
This recipe for Zesty Marinated Mushrooms uses classic Italian flavors—garlic, oregano, basil and a touch of crushed red pepper—combined with white wine vinegar, lemon juice and olive oil. It’s a tested water-bath canning recipe designed for half-pint jars so you can keep a shelf-stable jar of savory mushrooms on hand year-round.
Ingredients for Marinated Mushrooms
Makes four half-pint jars
- 3 pounds (1.4 kg) small button mushrooms (no more than 1½ inch / 4 cm across)
- ½ cup (120 ml) bottled lemon juice
- 1¼ cups (300 ml) white wine vinegar (5% acidity)
- 1 cup (237 ml) pure olive oil
- 5 garlic cloves, lightly smashed and peeled
- 1½ tsp (8 g) kosher salt
- 1½ tsp (2 g) dried oregano
- 1½ tsp (1 g) dried basil
- 1 tsp crushed red pepper flakes
Do not reduce the lemon juice or vinegar amounts—these acids are necessary for safe water-bath canning. Dry herbs are recommended for predictable results; you can adjust seasoning to taste.
Canning Marinated Mushrooms
This recipe has been tested for half-pint (240 ml) jars only. Using larger jars is not recommended for safety and quality.
1. Wash the mushrooms carefully and trim the stems to about ¼ inch (6 mm) long. Reserve trimmed stems for another use. Larger mushrooms can be halved if desired.
2. Place mushrooms in a large stainless-steel stockpot with the bottled lemon juice and enough fresh water to cover. Bring to a boil and, once boiling, boil for 5 minutes. Drain the mushrooms and pack them into sterilized half-pint jars, leaving ½ inch (13 mm) of headspace.
3. In a separate saucepan, combine the white wine vinegar, olive oil, garlic cloves, kosher salt, dried oregano, dried basil and crushed red pepper flakes. Bring the mixture to a boil over medium-high heat. Remove and reserve the garlic cloves from the brine—tuck one clove into each jar among the mushrooms.
4. Stir the hot vinegar-and-oil dressing and carefully ladle it over the mushrooms in each jar, keeping ½ inch (13 mm) headspace. Wipe the jar rims with a paper towel moistened with vinegar, apply lids and tighten bands to fingertip-tight.
5. Transfer jars to a canner of boiling water using canning tongs. Ensure the water covers the jars by 2 inches (5 cm). Cover the canner, return the water to a rolling boil and process jars for the time specified below, adjusted for altitude.
6. After processing, remove jars and place them on a towel-lined counter or wire rack to cool undisturbed. Allow jars to cool completely, preferably overnight, before removing rings, wiping jars clean and labeling.
Altitude Adjustments
Adjust processing time based on elevation to ensure safe preservation:
- 0–1,000 feet: process half-pint jars for 20 minutes
- 1,001–3,000 feet: process half-pint jars for 25 minutes
- 3,001–6,000 feet: process half-pint jars for 30 minutes
- Above 6,000 feet: process half-pint jars for 35 minutes
Notes and Serving Ideas
- The oil and vinegar will likely separate in the jar during storage. This is normal—shake the jar to recombine before using.
- The flavorful dressing that remains in the jar is excellent as an Italian-style vinaigrette for salads or as a marinade for chicken, pork or vegetables.
- Store marinated mushrooms in a cool, dark pantry. Once opened, refrigerate and use within a reasonable period for best quality.
- These marinated mushrooms pair beautifully with cheeses on a charcuterie board, tossed into mixed greens, or spooned over toasted bread for bruschetta-style appetizers.
Vegetarian Canning Recipes
If you enjoy canning vegetable-based meals, consider other shelf-stable, vegetarian-friendly canning projects such as carrot soup, butternut squash soup base, squash and bean soups, or Thai-style coconut squash soup. Home-canned soups and marinated vegetables expand meal options and make excellent pantry staples for quick, flavorful meals.
