Peel and dice pumpkin, onion, carrots, potatoes. Mince garlic.
Sautee onion and carrots in lard or butter (approx 2 Tbsp) until soft. Add garlic and sautee until fragrant, approx. 1 min. Remove vegetables from pan and transfer to slow cooker.
While the vegetables are sauteeing, rub the lamb roast with salt, pepper, and thyme.
Add lard to the now empty hot pan and sear the lamb roast approx. 2 mins on all sides. If you’re using cubed stew meat, don’t stir it around. Let it sit in the lard and sear for approx. 2 mins. Stir once, doing your best to overturn each cube and let it sear again without stirring. You’re not cooking the lamb through, you’re only searing the outside to improve its flavor.
Transfer seared lamb to the slow cooker and add potatoes, beans, grains, and stock. Add water or stock if needed to mostly cover the meat and vegetables.
Cook on low 5-6 hours. The grains will soak up much of the liquid, making a thick gravy stew. If you’d prefer a thinner stew, add more liquid towards the end of cooking time.
Season to taste before serving. Serve with thick hunks of bread generously slathered with butter. Or biscuits. Or soda bread. All good options. (chuckle)
