Delicious oven dishes for the cold days
27 November 2025
When the temperature drops and the days get shorter, there is nothing nicer than a tasty casserole. Winter vegetables are perfect for this: they are hearty, tasty and combine easily with other ingredients in the oven. In this blog you will find four tasty oven dishes that you can prepare without too much effort.
1. Brussels sprouts and carrot casserole
The Brussels sprouts and carrot casserole is a warm, classic oven favourite combining Brussels sprouts and carrot with creamy mashed potatoes, grated cheese and a layer of breadcrumbs for a crispy top. It's one of those dishes that immediately fills the kitchen with a nice smell and works perfectly on evenings when you're in need of something hearty and comforting. The oven does most of the work, while you can do something else in the meantime.
2. Broccoli casserole with Romesco sauce
A more surprising option is the broccoli casserole with Romesco sauce, which combines broccoli, mushrooms and potato with a Spanish Romesco sauce of paprika and almond. This sauce gives a deeper, slightly smoky flavour that immediately makes the dish special without being difficult. It is an ideal casserole for those who want something just a little different from the classic combinations, but still want to serve a nutritious meal.
3. Cauliflower and fennel from the oven with avocado-tahini dip
Cauliflower and fennel from the oven with avocado-tahini dip shows how simple vegetables from the oven can shine. The cauliflower and fennel caramelise gently, bringing out their natural sweetness, while the avocado-tahini dip provides a creamy, fresh counterpart. This dish is also completely plant-based and ideal as a light main course, but also does very well as a luxurious side dish during a meal.
4. Sweet onion and rettich (or radish) frittata
Finally, the sweet onion and rettich (or radish) frittata is an oven dish that combines simplicity and comfort nicely. The sweet onions provide softness, while rettich adds a subtle bite that keeps things interesting. The eggs and goat cheese create a fluffy, savoury frittata that is perfect as a hot lunch or quick supper. The dish proves that you can still create a lot of flavour with few ingredients.
