Do you cook sausages before putting in slow cooker?

Yes, it is generally recommended to cook sausages before adding them to a slow cooker. Browning the sausages in a skillet before placing them in the slow cooker helps enhance their flavor, texture, and appearance.

By browning the sausages first, you can achieve a caramelized exterior and seal in the juices, resulting in a more delicious and visually appealing dish. Once the sausages are browned, you can proceed with adding them to the slow cooker along with other ingredients to continue the cooking process.

If you don’t have time to brown the sausage, it’s okay to add it to the slow cooker raw.  Just know that the flavor will be a little bit different since you’re not searing the meat.

What vegetables go with sausage casserole?

Sausage casserole is a versatile dish that pairs well with a variety of vegetables. Here are some common vegetables that go well with sausage casserole:

  1. Onions: Onions add a savory flavor and enhance the overall taste of the casserole.

  2. Bell Peppers: Red, green, or yellow bell peppers add sweetness and a pop of color to the dish.

  3. Carrots: Carrots provide a subtle sweetness and add texture to the casserole.

  4. Celery: Celery adds a refreshing and slightly crunchy element to the dish.

  5. Potatoes: Potatoes can be diced or cubed and add heartiness and substance to the casserole.

  6. Mushrooms: Mushrooms offer an earthy flavor and a meaty texture that complements sausages well.

  7. Zucchini: Zucchini adds a light and fresh touch to the casserole and pairs nicely with sausages.

  8. Tomatoes: Fresh or canned tomatoes provide acidity and contribute to the rich sauce of the casserole.

Feel free to mix and match these vegetables according to your taste preferences. You can also add other vegetables of your choice to customize the casserole and make it your own.
