Ingredients for White Bean Casserole

• 4 medium potatoes 

• 800 g cooked white or lima beans (3 cups)

• 2 medium onions, chopped

• 3 cloves of garlic, minced

• 2 tbsp avocado oil

• 400 g canned tomatoes (14 oz can)

• 100 g grated aged cheese (1 cup)

• ½ tsp each dried onion and garlic powder

• Salt, pepper, and herbs (like thyme or parsley, optional)

You can use canned or home-cooked beans — just drain and rinse before adding them.

Step-by-Step Instructions

• Peel and slice the potatoes. Parboil for 20-25 minutes until just tender.
• In a large pan, heat avocado oil. Add onions and garlic, sauté until golden and fragrant.
• Stir in canned tomatoes, cooked beans, and seasoning (dried onion, garlic powder, salt, and pepper). Simmer for 10 minutes.
• In a casserole dish, layer potatoes and bean mixture. Top with grated cheese.
• Bake at 190°C (375°F) for about 25–30 minutes until bubbling and golden on top.
• Let rest 5 minutes before serving. Pair with a green salad or crusty bread.

💡 Tips & Variations

• Add more veggies: Mix in spinach, kale, or zucchini for extra color and nutrition.

• Go vegan: Swap the cheese for vegan cheese or sprinkle nutritional yeast for a dairy-free twist.

• Change up the beans: Try cannellini, butter beans, or chickpeas for a slightly different texture.

• Boost the flavor: Add a pinch of smoked paprika, chili flakes, or Italian herbs for extra depth.

• Oil options: If you don’t have avocado oil, olive oil works perfectly too.

• Make it ahead: Assemble the white bean casserole in advance and bake it just before serving — great for meal prep or entertaining.

• Add crunch: Top with breadcrumbs or crushed nuts for a crispy, golden finish.

🧊 Storage & Reheating

• Refrigerate: Let the casserole cool completely, then store leftovers in an airtight container in the fridge for up to 3 days.

• Freeze: Portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

• Reheat in the oven: Warm at 180°C (350°F) for about 15–20 minutes, or until heated through.

• Reheat in the microwave: Heat individual portions on medium power for 2–3 minutes, stirring halfway to ensure even warmth.

💡 Tip: If the casserole seems a bit dry after reheating, drizzle a little water or olive oil over the top before warming — it helps restore that cozy, creamy texture.
