Description

A hearty and comforting Crockpot Sausage Casserole featuring browned sausages, tender potatoes, carrots, and onions slowly cooked in a rich tomato and herb broth. Perfect for an easy, hands-off meal with deep, savory flavors developed over hours of slow cooking.


Ingredients

Scale

Sausages

  • 1 lb (450g) sausages (pork, chicken, or smoked)

Vegetables

  • 1.5 lbs (700g) potatoes, peeled and diced
  • 3 carrots, chopped
  • 1 large onion, chopped
  • 3 cloves garlic, minced

Tomato Mixture

  • 1 can (14.5 oz) chopped tomatoes
  • 2 tablespoons tomato paste
  • 1 cup beef or vegetable broth

Herbs & Seasonings

  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 1/2 teaspoon dried oregano
  • Salt and pepper to taste

Other

  • 1 tablespoon olive oil


Instructions

  1. Brown the Sausages: Heat olive oil in a skillet over medium-high heat. Add the sausages and cook, turning occasionally, until browned on all sides. This step adds flavor and seals in juices.
  2. Prepare Vegetables: While the sausages brown, peel and dice the potatoes, chop the carrots and onion, and mince the garlic to ensure everything is ready for layering.
  3. Layer Vegetables in Crockpot: Place the diced potatoes, chopped carrots, onion, and minced garlic evenly in the bottom of the crockpot to create a flavorful vegetable base.
  4. Add Sausages: Arrange the browned sausages on top of the layered vegetables inside the crockpot for even cooking and flavor infusion.
  5. Mix Tomato Sauce: In a bowl, combine the chopped tomatoes, tomato paste, beef or vegetable broth, dried thyme, dried rosemary, dried oregano, salt, and pepper, stirring to mix well.
  6. Pour Sauce Over Ingredients: Carefully pour the tomato and herb mixture evenly over the sausages and vegetables in the crockpot, ensuring everything is well coated.
  7. Slow Cook: Cover the crockpot with its lid and cook on LOW for 6-8 hours or HIGH for 3-4 hours until the vegetables are tender and sausages are fully cooked.
  8. Serve: Before serving, gently stir the casserole to distribute ingredients. Optionally garnish with fresh herbs for added color and flavor.

Notes

  • Use your preferred type of sausage such as pork, chicken, or smoked depending on flavor preference.
  • To speed up cooking, use the HIGH setting but for best flavor and tenderness cook on LOW.
  • Fresh herbs like parsley or thyme can be added as a garnish to enhance presentation and taste.
  • For a thicker sauce, remove the lid in the last 30 minutes to allow some liquid to evaporate.
  • This dish reheats well and flavors intensify after resting overnight.
