When I first started blogging I adopted the tagline “home is where your story begins,” Making memories with my family and telling stories is an important part of my identity.

With two adult married children, two grandsons and another on the way, and only one kid living at home, we cherish every opportunity to create memories together.

We have many Christmas traditions but interestingly enough, none really center around food. Unlike Thanksgiving, where the menu is set in stone and repeated every year, we don’t have a set menu for our time together. 

For us, it’s just all about being together and enjoying those qualities that make us family: sharing laughter; reminiscing over family stories and playing games around the table. (Although playing games is a lot more difficult with little creatures running around!)

We’re not perfect and while everyone has their little (or big) quirks, we know God divinely brought us together through both the bond of blood and adoption.

It’s the most wonderful time of the year!

I love using my slow cooker for easy recipes (even though my hubby can’t stand it in the summer!)

I’ve been looking for a slow cooker tomato basil soup recipe that would fill the house with scrumptious smells while we celebrate the season together.

I have to confess I wasn’t really a tomato soup lover, but I have changed my tune thanks to this recipe.

My secret ingredient? Marinara sauce and roasted bell pepper strips. 

I’d like to show you pictures of each step but I know y’all are smart cooks.

Plus I had a little run in with a blender. Let’s just say I baptized our new countertops and bead board! You can definitely leave out that step!

You could also substitute dried basil for fresh.

  1. I can`t wait to try it… It says winter comfort foods but i`ll make it now (in the summer).
    Who says great tomato soup is just for the winter?

  2. I love tomato soup. I am going to have to try this but in my instant pot. I have never been a planner and i always forgot to use tge crockpot. I got an instant pot and LOVE it. Reading this blog i have to say I never had a set menu for Christmas while tge kids were little and we lived 4 hours from family. I wanted to play with the girls. So the got games and coloring books with other stuff and we all spent the day together. The amazing thing was their military father worked much shift work and MANY holidays but in 24 years of active duty service he only worked on Christmas and it was nights. Though the military sent him to Alaska for a year. He came home Christmas. Jas was 15 i think and Helen was 11. He got leave for Christmas. He came home in nearly dec. We finished Christmas shopping early. Thankfully because i had emergency gall bladder surgery Christmas Eve and was in the hospital until New Years eve. A blimp in the road but we worked it out.

  3. 5 stars
    Wonderful comfort food during quarantine! I was so very bummed that my $5 worth of basil got pushed to the back of the fridge and froze so it was unusable, but I was pleasantly surprised by how delicious this was even with just dried basil instead. Followed the recipe except for the crushed tomatoes I used 2 cans of diced tomatoes with italian seasoning (I could have pureed the soup but my one daughter just picked out the small chunks of tomatoes).

    Whole family (including 3 teenagers) liked it so definitely giving it a thumbs up. In fact, my college son said he wants the recipe so he can make it for his housemates in the fall. That’s a big compliment!
