While trying to spend more time working on the blog during this total nightmare of a COVID19 outbreak, I have been trying to update old recipes, such as this Slow Cooker Tomato Basil Soup Recipe with information to help my readers…right now, we are in week four of lock down in Miami. We are allowed to go grocery shopping, or to get tested, but that is pretty much it. I haven’t left my home since Saint Patrick’s Day, except to buy cigarettes at the drive through convenience store.

Slow Cooker Tomato Basil Soup Recipe 

Ingredients

• 6 cups tomatoes pureed, or substitute 3 cans diced tomatoes
• 1 cup onion, diced
• 4 cups chicken broth
• 1/4 cup basil, finely chopped
• 1 tsp oregano
• 2 cups half and half
• 1/2 cup flour
• 1/2 cup butter
• 1 cup Parmesan cheese, freshly grated
• salt and pepper to taste

Directions

If using fresh tomatoes, puree up 6 full cups and don’t drain any liquid. (if using cans, don’t drain liquid) Pour into slow cooker.

Add onions, oregano, basil, half and half and finally the chicken broth. On low cook covered for 5 hours. Stir occasionally.

About 1/2 hour before you’re ready to serve, make up a quick roux. Use small saucepan over low heat to melt butter, add flour and stir for about 3-5 minutes. Don’t let this burn! Add in 1 cup of cooked soup and stir until super smooth.

Lumpy tomato basil soup is yucky. Pour this back into your slow cooker and stir to incorporate well. Continue to cook on low for about 30 minutes until soup is thickened.

Add Parmesan cheese, let sit for 5 minutes until melted. Salt and pepper to taste.

Grill up some cheese sammies and serve hot!

See, comfort food! We make this using our fresh tomatoes in the summer and use cans in the winter. It’s awesome after being outside building snowmen with the kiddos on cold days too!

What kind of sandwich should you make to go alongside a slow cooker tomato soup? DUH! Always a grilled cheese, of course! I love using sharp cheddar and mozzarella for extra cheesy goodness. Of course, any old kind of cheese will do, but cheddar is the BEST! I can even get behind a Kraft cheese slice if that is really all you have…yes, I am picky like that! I prefer REAL cheese, not cheese food. But I have clearly eaten a Kraft Single or two in my day – no judgement here! I just want you to have the very best grilled cheese sandwich you could possibly have! Shoot, I would even approve of grilled BRIE sandwiches! YUM!
