Tomato bisque was one of the first things I ever learned to make in a restaurant. That may sound like a simple task, but it requires adding ingredients in a specific order to really build the most flavor. This tomato bacon bisque is no different! It has so many layers of flavor–smokey bacon, sweet onions, tangy fennel, spicy chilies, acidic tomatoes, fresh herbs. Honestly, this is probably one of the best soups I’ve ever made and it’s definitely inspired by my humble restaurant beginnings. Nothing is better than dipping a grilled cheese into this creamy bacon-y soup on a cold day. NOTHING! So get to the kitchen and make this glorious bisque ASAP!
What is a bisque?
Traditionally a bisque was a creamy soup of French origins made using shellfish or and broth from the shells of lobsters, langoustine, crab, shrimp, etc. Since its early origins, the definition has been expanded to refer to a class of pureed, thick soups made richer by using cream.
Do I have to use fennel in this recipe?
No! If fennel really isn’t your jam, you can omit it. However, I think it gives the soup glorious flavor and adds to its texture and richness.
Can tomato bacon bisque be made gluten-free?
Great news! The soup is already gluten-free, just omit the croutons or sub in your favorite gluten-free bread when making them.
Can I make it vegan?
I would say, yes. You can omit the bacon (or sub meatless bacon) and use olive oil in place of the fat to cook the onions and fennel in. Swap coconut milk or cream for the heavy cream and vegetable broth for the chicken. If you do make it vegan, I would love to hear how it turned out!
Can I freeze the extra tomato bacon bisque?
Absolutely! Just make sure the bisque is completely cooled to room temperature. I load up gallon ziplock bags with the cooled bisque and freeze them flat. It really helps save space in the freezer!
What are calabrian chilies? Can I sub in something else?
Calabrian chilies are chilies from the Calabria region of Italy and they are out of this world good! They are a bit spicy, but they also have a lovely fruitiness to them. I use them in pretty much any recipe that could use a boost of flavorful heat or anywhere that I would use crushed red pepper flakes. If you can’t find Calabrian chilies, you can substitute 1-2 teaspoons of crushed red pepper flakes (depending on your heat tolerance and taste). If you shop at Trader Joe’s, the ” Italian bomba paste” is chopped Calabrian chile and I stock up on those little jars like crazy. You can also find some on Amazon here.
How do I render bacon?
Rendering bacon is to cook it very slowly over low heat so that the fat slowly melts from the meat and you’re left with crispy bacon pieces. As the fat melts from the meat, the bacon meat portion cooks in its own fat and ends up gloriously crispy AND you’re left with some liquid gold bacon fat. Rendering starts by adding the bacon to a cold pan and then bringing it up over very low heat. As the bacon cooks, the fat will slowly melt and then the bacon will get crispy. This simply requires time and patience and an occasional stir!
