Your sun oven isn't just for summer cooking – it's perfect for creating warm, comforting winter dishes while saving energy. You can prepare a hearty vegetable stew packed with seasonal produce, a classic lasagna layered with cheese and spinach, or a perfectly roasted herb chicken that stays moist and tender. For something sweet, try a butternut squash casserole topped with nutty streusel or an apple cinnamon cobbler that'll fill your home with cozy aromas. These five recipes make the most of winter sunlight, and there's much more to discover about cooking with nature's own heat source.
Hearty Winter Vegetable Stew

While traditional stews often rely on meat for heartiness, this winter vegetable stew delivers rich, satisfying flavors through a medley of seasonal vegetables and savory seasonings.
You'll need olive oil, onion, garlic, carrots, potatoes, mushrooms, and celery as your base ingredients.
Begin by sautéing onions and garlic in olive oil until fragrant. Add your chopped vegetables and cook until they start to soften.
Pour in vegetable broth, apple juice, and soy sauce, then bring to a simmer. For deeper flavor, incorporate bay leaves, herbs, and a splash of balsamic vinegar. This healthy meal provides approximately 235 calories per serving.
Let it simmer for 30-35 minutes until the vegetables are tender.
To thicken your stew, you can either blend a portion or add cornstarch. It's perfect served with crusty bread and stores well for future meals.
Classic Sun-Baked Lasagna
Although solar cooking might seem challenging in winter, a hearty lasagna proves to be an ideal dish for your sun oven.
You'll need ricotta, Parmesan, mozzarella, whole-wheat lasagna noodles, tomato sauce, and an egg. Mix the ricotta, Parmesan, and beaten egg, then blend in spinach and pesto for extra flavor. Whether you choose homemade or store-bought pesto, both options work well in this recipe.
Layer your ingredients starting with tomato sauce, followed by noodles and the cheese mixture. Place the baking dish in an oven bag and position your solar oven in direct sunlight between 10 a.m. and 3 p.m. Cook until the oven reaches 300°F, usually 1½ to 2 hours.
Add mozzarella on top for the final 10 minutes of cooking. Let your lasagna rest before serving, and use a thermal box to keep it warm if needed.
Roasted Herb Chicken

Since winter days provide less sunlight, making a flavorful herb-roasted chicken requires strategic timing in your sun oven. Start by preheating your sun oven early, then prepare a 5-pound whole chicken by removing giblets and trimming excess fat.
Mix softened butter with chopped garlic, rosemary, and your choice of thyme, sage, or parsley. After patting the chicken dry, gently loosen the skin and spread your herb-butter mixture underneath it. You'll want to season generously with salt and pepper, then place the bird in a lidded roasting pan. This recipe results in just 24 calories per serving when divided among six people.
For extra flavor, stuff the cavity with carrots and onions. Cook until the internal temperature reaches 175°F in the thigh, typically about 2 hours. Let it rest for 10 minutes before carving. While the skin won't crisp, you'll enjoy exceptionally moist meat.
Winter Squash Casserole
A hearty winter squash casserole makes the perfect companion to your sun-oven roasted chicken.
You'll need a large butternut squash, though kabocha or acorn varieties work well too. After washing and halving your squash, coat it with butter, brown sugar, and salt before placing it in your sun oven until tender.
Once your squash is soft, mash it and prepare a delicious streusel topping with:
- Melted butter, brown sugar, and flour mixture
- Chopped pecans or walnuts
- A sprinkle of warming cinnamon
Transfer your mashed squash to a casserole dish, add the topping, and return it to your sun oven until golden brown.
You can prep this dish a day ahead and store it in the fridge, making it perfect for busy winter gatherings.
Apple Cinnamon Cobbler

When winter temperatures drop, an apple cinnamon cobbler in your sun oven brings comforting warmth to any gathering.
Start by peeling and slicing 5-9 large apples, choosing from Fuji, Honeycrisp, Granny Smith, or Pink Lady varieties. Toss them with lemon juice, vanilla extract, brown sugar, cinnamon, and cornstarch.
Pour your apple mixture into a greased baking dish and cook until the apples start to soften.
While they're baking, prepare the topping by combining flour, sugars, and salt, then cut in cold butter until you've got coarse crumbs. Alternatively, you can make a batter with flour, sugar, and melted butter.
Spread your topping over the apples and bake until it's golden brown and bubbly.
Don't forget to let it cool briefly before serving with vanilla ice cream.
