I have a favorite Low Carb Sweet Italian Sausage Recipe that I make several times a month. It’s a mixture of sweet Italian sausage, mushrooms, spinach or kale and spaghetti squash. It’s super delicious and I’ve never served it without rave reviews.

Spaghetti Squash can be the start of so many healthy, grain free recipes. I encourage you to master the art of making spaghetti squash. Actually, I’m teasing you. It’s super easy to make. You can make it stove top like I did in this recipe or roast in the oven.

What kind of Italian sausage do you use?

I am a member and affiliate for ButcherBox.  It’s the best Italian sausage we’ve ever had. We make this casserole and this sausage crusted pizza a few times a month. ButcherBox is a subscription service that delivers vacuum sealed, high quality sourced, meat chicken and seafood to your door at an affordable price. While they offer various curated boxes, I customize ours every month making sure Italian sausage is part of my box. 

What greens work best in this Sweet Italian Sausage Casserole?

I think kale is probably best but spinach works well also. Any green you want to add for color and interest is fine too. I hope you know you can freeze kale and spinach, and always have greens available for these kind of recipes.

Secret Ingredient also my favorite spice 

I love piment d’ espelette and is a go to for spicing up everything from vegetable dishes to seafood. 

What is piment d’espelette? 

Piment d’ espelette,  made from the Espelette pepper, also known as Piment d’Espelette, is a chili pepper cultivated in the French commune of Espelette, Pyrénées-Atlantiques. It is mildly hot, measuring up to 4,000 Scoville Heat Units. It’s sweet, spicy and smoky without overpowering a dish.  I like the way it gives heat to a dish, more nuanced than red chili flakes (which you could also use). 

You could cover this with pecorino cheese as I did or even use mozzarella. You could even dollop ricotta cheese in this casserole. 

I love my Le Creuset Braiser, because it goes from stove top to oven. A cast iron pan would do the same thing.

This is a flexible recipe. You could use turkey sausage if you choose. You could also choose a different meat, even leftover roast chicken, leftover carnitas

How to Sauté Mushrooms

I use either white button mushrooms or cremini mushrooms. I like to slice my own, saute in butter or oil, keeping them separate so they brown a little, instead of steam. That brings out a true mushroom flavor. Mushrooms are a great partner for sausage and for spinach and are a great addition to this recipe. If you hate mushrooms, skip them. It’s that simple. You might choose to add in some chopped sun-dried tomatoes instead. 

This is a an easy dish, very forgiving. Make sure you use enough salt and pepper and a little heat to bring it together. Don’t plan on leftovers. You probably won’t have any.

      Very good one dish meal. I added onions/garlic as well as fresh basil and a bit of rosemary. Adding the mozzarella was a good tip.
