Oven Roasted Tomatoes

So sorry about this hit and miss posting I've been doing lately. Canning is hard work plus I've had and have a cold or something. My energy has gone by the wayside. I am making Oven Roasted Tomatoes for the freezer today. This is adapted from an old Southern Living recipe (2009). I have used canned tomatoes to make this, but with all the beautiful garden tomatoes now I'm using fresh today. I use these on pizza, in chili, etc.

Makes about 2 cups
print recipe

3 (28-ounce) cans whole tomatoes, drained and halved, or about 5 pounds fresh
3/4 cup coarsely chopped sweet onion
1/2 cup loosely packed fresh basil leaves, chopped
1/3 cup olive oil
5 large cloves garlic, halved
1 1/2 teaspoons dried oregano
1/2 teaspoons freshly ground pepper

1. Preheat oven to 300 degrees F. Place tomato halves in a colander, and press gently to remove excess liquid.

2. Stir together tomatoes, onion, and remaining ingredients in a large bowl. Place tomato mixture in a single layer in a aluminum foil-lined 15x10-inch jelly-roll pan.

3. Bake at 300 degrees F for 2 1/2-3 hours or until tomato mixture is deep reed and lightly browned, stirring every 45 minutes. Cool in pan on a wire rack 15 to 200 minutes or until completely cool. Store in an airtight container in refrigerator up to 3 days.

TO FREEZE: Place tomato mixture in an airtight container, and freeze up to 3 months. Thaw in refrigerator 24 hours.
