Sausage Recipe: Easy Sausage and Bean Casserole

This sausage and bean casserole pairs browned pork sausages with carrots, tomatoes and creamy white beans in a savoury, gently herbed sauce. It is a practical, British-inspired one-pan supper: the sausages finish cooking in the tomato broth, so their flavour enriches the sauce as well.

Ingredients

8 uncooked pork sausages, about 1½ lb (680 g), preferably medium-sized
1 tbsp olive oil (15 ml)
1 large yellow onion, about 1½ cups chopped (225 g)
2 medium carrots, about 1½ cups chopped (180 g)
2 celery stalks, about 1 cup chopped (100 g)
3 garlic cloves, finely chopped, about 1 tbsp (9 g)
1 tbsp tomato paste (15 ml; about 16 g)
1 tsp smoked or sweet paprika (2 g)
1 tsp dried thyme (1 g)
¼ tsp red pepper flakes (about 0.5 g), optional
1 can cannellini or butter beans, 15 oz (425 g) net weight, drained and rinsed; about 1½ cups (255 g) drained
1 can chopped tomatoes, 14.5 oz (411 g)
1½ cups chicken stock (360 ml), preferably lower-sodium
1 tbsp Worcestershire sauce (15 ml)
1 bay leaf
½ tsp fine salt (3 g), plus more to taste
¼ tsp freshly ground black pepper (about 0.5 g)
2 tbsp chopped fresh parsley (8 g), to finish

Instructions

Prepare the ingredients. Allow about 20 minutes to chop the onion, carrots, celery and garlic, drain and rinse the beans, and measure the remaining ingredients. Keep the sausages refrigerated until you are ready to brown them. If they are linked together, separate them without piercing the casings; keeping the casings intact helps the sausages stay juicy.
Brown the sausages, 10 minutes. Set a large, heavy lidded skillet or Dutch oven over medium heat and add the oil. When it shimmers, add the sausages in a single layer. Turn them every couple of minutes until well browned on several sides, about 10 minutes. They do not need to be cooked through at this point. Transfer them to a plate, leaving the rendered fat and browned bits in the pan. If the pan looks dry, add a teaspoon of oil; if there is a large pool of fat, carefully spoon off most of it.
Soften the vegetables, 8 minutes. Add the onion, carrots and celery to the same pan. Cook over medium heat, stirring and scraping up browned bits, until the onion has softened and the carrots are beginning to lose their raw, firm edge, about 8 minutes. If the vegetables start sticking before they soften, add a tablespoon of water rather than turning the heat very high.
Build the sauce, 4 minutes. Stir in the garlic, tomato paste, paprika, thyme and optional red pepper flakes. Cook for 2 minutes, stirring so the garlic does not scorch and the paste darkens slightly. Add the tomatoes, stock, Worcestershire sauce, bay leaf, salt and black pepper. Stir well, then bring the liquid to a gentle simmer, which should take about 2 minutes.
Simmer the sausages, 24 minutes. Nestle the browned sausages into the tomato mixture and pour in any juices from the plate. Cover the pan, reduce the heat to low and simmer gently for 24 minutes. Check that the sauce bubbles softly rather than boiling hard; a vigorous boil can split sausage casings and make the meat less tender. Turn the sausages once halfway through if they are not mostly submerged.
Add the beans and finish, 4 minutes. Stir in the drained beans, cover again and simmer for 4 minutes, just until they are hot and the sauce has thickened slightly. Check the centre of the thickest sausage with a food thermometer, avoiding the pan and any bone if present. Because sausage is ground meat, USDA FSIS guidance sets its safe minimum internal temperature at 160°F (71°C). If a sausage has not reached that temperature, keep simmering and check again after a few minutes. Remove the bay leaf, taste the sauce and adjust the salt or pepper. Scatter the parsley over the casserole and serve hot.

Tips

Choose sausages of a similar size. Evenly sized links brown and finish cooking at roughly the same pace. If yours are especially thick, the centre may need a few extra minutes; use the thermometer rather than relying on colour or the stated cooking time alone.
Keep the simmer gentle. A low, steady simmer cooks the sausages through without toughening them or breaking their skins. If the sauce thickens too much before the sausages are ready, stir in stock or water a tablespoon at a time.
Season after the beans are added. Sausages, stock and Worcestershire sauce can all contribute salt, and brands vary. Taste the finished sauce before adding more; lower-sodium stock makes the amount easier to control.
Use a suitable pan and avoid crowding. A broad, heavy pan gives the sausages room to brown and helps the vegetables soften evenly. If your pan is small, brown the sausages in two batches rather than steaming them in a crowded layer.

Serving Suggestions

Serve the casserole in shallow bowls so each portion gets sausages, beans, vegetables and plenty of sauce. Crusty bread, toasted sourdough or a warm baguette is useful for scooping up the tomato broth. For a more substantial plate, spoon it over mashed potatoes, buttered egg noodles or plain rice; potatoes are especially good at catching the sauce without competing with its savoury flavour.

A simple green vegetable makes a fresh contrast. Try steamed green beans, broccoli, cabbage or peas, or serve a crisp green salad with a lightly dressed vinaigrette. If you want a little extra richness, finish each bowl with a small drizzle of olive oil or a pinch of chopped parsley. Keep any extra seasoning at the table so diners can adjust their own servings.

Variations

Change the beans: Great Northern beans, navy beans or butter beans all work in place of cannellini beans. Chickpeas are another option, though they are firmer and have a nuttier bite. Drain and rinse canned beans before adding them. If using dried beans, cook them separately until tender first; do not add uncooked dried beans directly to this quick casserole.

Use another sausage: Chicken or turkey sausages can replace pork sausages, but their size and fat content may change the browning time and the flavour of the sauce. Check the package for handling instructions and use a food thermometer; poultry sausages need to reach 165°F (74°C), the USDA FSIS safe minimum for poultry. A spicy pork sausage works too, but reduce or omit the red pepper flakes.

Add greens or extra vegetables: Stir in a couple of handfuls of chopped kale or spinach during the final 4 minutes, adding a splash of stock if the pan becomes crowded. Diced red bell pepper can go in with the carrots and celery. For mushrooms, brown them after the sausages and before adding the other vegetables so they release their liquid and develop colour instead of watering down the sauce.

Make the sauce more or less robust: Use sweet paprika for a mild, rounded flavour or smoked paprika for a smoky note. A teaspoon of dried rosemary can replace the thyme, although rosemary is stronger, so use a light hand. For a thicker casserole, uncover the pan for the final few minutes and simmer gently; for a looser, soupier bowl, add a little more stock. Worcestershire sauce contains anchovies, so for a fish-free alternative use soy sauce or a suitable vegetarian Worcestershire-style sauce; either will alter the savoury flavour slightly.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking. Transfer them to a shallow, airtight container so they cool promptly, and keep them refrigerated for 3–4 days. The sauce may thicken as it chills because the beans absorb some liquid; that is normal. Add a splash of water or stock when reheating if you prefer a looser consistency.

Reheat only the portion you plan to eat, either in a covered saucepan over medium-low heat or in a microwave-safe dish, stirring or turning the food partway through so it heats evenly. Reheat leftovers to 165°F (74°C), checking the centre with a food thermometer. If warming on the stove, bring the sauce to a gentle simmer while the sausages heat through, and add a little liquid if needed. Do not leave the casserole at room temperature for more than 2 hours. You can freeze it in airtight portions for up to 3 months for best quality; thaw overnight in the refrigerator and reheat to 165°F (74°C).

Frequently Asked Questions

Can I make this sausage casserole ahead?
Yes. Cook it fully, cool it promptly and refrigerate it in a covered container within 2 hours. It keeps for 3–4 days in the refrigerator. Reheat the portion you need to 165°F (74°C), adding a splash of stock or water if the sauce has thickened.

Can I use precooked sausages?
Yes, but they need less cooking. Brown them briefly for colour, then simmer them in the sauce only long enough to heat through, following the package instructions. Add the beans near the end so they do not become mushy. If the sausages are made from ground meat, reheated leftovers still need to reach 165°F (74°C).

Why are my sausages splitting?
A hard boil, very high heat or repeatedly piercing the casings can cause them to split. Brown them over medium heat, then keep the sauce at a gentle simmer and turn the links carefully. A split casing is not a safety problem if the sausage is cooked to its required temperature, but it can let more juices escape.

How can I thicken the sauce?
Remove the lid for the final few minutes and let the sauce reduce gently, stirring now and then so the beans do not stick. You can also mash a few beans against the side of the pan and stir them back in. Avoid adding flour directly to the finished casserole, as it can form lumps unless it is first mixed into a smooth slurry.

Can I make it without Worcestershire sauce?
Yes. Leave it out, or replace it with an equal amount of soy sauce for a salty, savoury note. A vegetarian Worcestershire-style sauce is another option. Since the alternatives vary in saltiness, taste the finished dish before adding more salt.

What should I do if the sausages are cooked but the sauce is thin?
Lift the sausages out briefly and simmer the sauce uncovered until it reaches the consistency you like, then return the sausages to the pan. This prevents the meat from cooking longer than necessary. If the sauce is already thick but the sausages are not at a safe temperature, add a small splash of stock and continue cooking gently until they reach the required temperature.
