1 small onion, chopped
1 clove garlic, minced
1/2 red bell pepper, chopped
1/2 yellow bell pepper, chopped

1/2 tsp smoked paprika
1/2 tsp mixed herbs
Salt and pepper, to taste
1/4 tsp chilli flakes (optional, for extra heat)
Fresh parsley, chopped (to garnish)

Method:

Prepare the Sausages

To enhance the flavour, lightly brown the sausages in a non-stick pan over medium heat for about 5 minutes, until they’re golden. This step is optional, but it adds depth to the dish. Transfer the sausages to your slow cooker.

Add the Vegetables and Beans

Next, add the chopped onion, garlic, red and yellow bell peppers, mushrooms, spinach (or kale), and cannellini beans to the slow cooker.

Add the Liquids and Seasonings

Pour in the tinned chopped tomatoes and chicken stock. Sprinkle in the smoked paprika, mixed herbs, and a pinch of salt and pepper. If you like a bit of spice, stir in the chilli flakes.

Cook the Casserole

Cover the slow cooker and cook:

On low for 6-8 hours, or
On high for 3-4 hours

The sausages will be fully cooked, and the vegetables tender and flavourful.

Serve and Garnish

Before serving, taste and adjust the seasoning if needed. Ladle the casserole into bowls and garnish with freshly chopped parsley.

Serving Suggestions

This casserole is hearty enough to stand alone, but you can pair it with:

Crusty wholemeal bread for dipping
Creamy mashed potatoes
Steamed quinoa or brown rice

Tips for Success

Choose the Right Sausages: Look for sausages with a high protein content (10-12g per sausage) and low fat for the healthiest option.
Add More Veg: Feel free to throw in extra vegetables such as courgettes, carrots, or green beans.
Storage:Store leftovers in the fridge for up to 3 days or freeze portions for up to 3 months.

Why Slow Cooking Works for This Recipe

The slow cooker allows the sausages to absorb all the flavours from the vegetables and seasonings while keeping them tender and juicy. It’s a no-fuss way to create a flavour-packed, nutritious meal.

Whether you’re meal-prepping for the week or need a comforting dinner on a cold evening, this high-protein slow cooker sausage casserole is the perfect choice. Enjoy the rich, warming flavours with the satisfaction of knowing you’re eating something that’s good for you too!
