Flavor notes

The red chili pepper choice is up to you, as the point of the chilies here is primarily to add spiciness. The flavor of the chilies (outside of the heat) is not essential in this recipe, as the sausage and vegetables take the lead.

Red jalapeño peppers are an excellent choice for spicy sausage casserole. Their low-medium heat (2,500 to 8,000 Scoville heat units) is something most anyone can enjoy. Or, for something spicier, try fresh cayenne (30,000 to 50,000 SHU) or even Thai peppers (50,000 to 100,000 SHU).

Of course, you could opt to omit the fresh chili altogether. You’ll still get a touch of warmth from the dish, coming from the paprika, chipotle flakes, and black pepper. And that may be just enough for some.

The oven does most of the work. The sausages get a 10-minute head start on their own, then the vegetables, spices and broth go in, the dish gets covered, and it bakes until the sausages are cooked through and the vegetables are soft. Wondering how you’ll know it’s done? Pork sausage is safe at 160°F, so check one with a thermometer if you’re not sure. Want to see it come together first? There’s a full video below, along with the ingredients and steps.

Adaptation ideas

I use tomatoes, red peppers, and onion in this recipe, and they give the dish a delicious garden-fresh undertone. But don’t be afraid to experiment to make your own take on this spicy sausage casserole. I’ve made it with a lot of variations in the past, and each adds fun depth to the dish. Try it with added carrots, turnips, or zucchini for something new. All work well, and so would many other vegetables.

  • Want it hotter? Go with two fresh cayenne or Thai peppers, or add an extra pinch of chipotle flakes.
  • Want it milder? Use a single red jalapeño, or leave the fresh chili out and let the paprika and chipotle flakes carry it.
  • Different sausage: Hot Italian sausage doubles down on the spice, while chicken sausage makes a lighter casserole.
  • Heartier: Feeding a crowd? Stir in a can of drained white beans or chickpeas with the tomatoes to stretch it a little further.

Serving ideas

As to the serving, this recipe can be either a hearty side or a full meal. Serve it with potatoes, rice, or (my favorite) some crusty bread with fresh butter. It also works well with pasta.

  • With crusty bread: Tear off a hunk, butter it, and use it to mop up the sauce.
  • Over mashed potatoes: Spoon the sausages and sauce right on top.
  • With rice or pasta: A short pasta like penne catches the chunky sauce.
  • With a green salad: Something crisp and simple balances all that richness.

Storage notes

Lastly, this dish is great for storing. The leftovers are nearly as good as the day it was made. Keep in airtight containers in the refrigerator for up to three days or freeze for up to two months for those nights when you are too tired to cook.

When you reheat it, warm it in the oven or on the stove until it’s steaming hot all the way through, and add a splash of broth if the sauce has thickened up in the fridge. Got it frozen? Let it thaw in the fridge overnight first.
