This quick and easy vegetable casserole with roasted fennel and beans is a delicious, warming vegetarian family dinner idea. Nourishing and filling it makes a perfect healthy meal to enjoy on a chilly night.

This easy vegetarian casserole with fennel is a combination of different textures and contrasting flavours, which together create a rich, satisfying, delicious dish. If you've ever tasted roasted fennel you will know that it's quite different from raw. When cooked its aniseed flavour is toned down and the fennel becomes sweet, mellow and soft. Which is exactly how it turned out in this vegetable casserole.
I decided to roast the fennel before adding into the casserole in order to preserve all of its flavour. I made the sauce separately, then combined it with the fennel (and added the feta) before bringing all the ingredients together into one dish and briefly broiling in the oven.
If you are a fan of fennel try my pasta bake with fennel and cherry tomatoes. You might also like this aromatic, vibrant beetroot fennel soup with kale.
To make the sauce I used a combination of sweet and tangy vegetables, as well as a splash of wine and sun dried tomatoes for a richer flavour. I added beans for bulk and protein. The sweet roasted fennel is absolutely delicious with the rich vegetable bean sauce and the tangy feta.
Equipment you'll need
- Cutting board and knife
- Large baking sheet and parchment paper
- Large shallow oven proof casserole dish with lid and spatula
How to make easy vegetable casserole with roasted fennel
There are 3 separate parts to this recipe, 2 of which can be cooked simultaneously so the recipe doesn't take very long to make.
1.Start by roasting the fennel. Spread it over a baking sheet lined with parchment paper, season and drizzle with a little oil (about 2 tablespoons).
2. Roast in a preheated oven at 200 C for about 30 minutes or until tender, turning over half way through. Remove from the oven and increase the oven temperature to 220 C.
3. While the fennel is in the oven start making the vegetable sauce. (By the time the fennel is ready the sauce should be more or less finished). Heat up 2 tablespoons of oil, add the onion, garlic, celery and bay leaf and fry gently until softened for 3 minutes.
4. Add the wine, tomatoes, beans (along with the water from the can), carrots and peppers and stir.
5. Add the sun dried tomatoes, oregano, season to taste, stir thoroughly, cover and bring to the boil then simmer for 25 minutes stirring occasionally.
6. Tuck the roasted fennel pieces into the sauce, scatter the crumbled feta over the top and drizzle with a little oil. Place in the upper part of the oven and broil for 10 minutes (220 C).
This rich and delicious vegetarian casserole takes under 50 minutes to make from start to finish but it tastes like it's been cooking for 4 slow hours!
Top tips for making roasted fennel vegetable casserole
- Fennel: Use a large baking sheet to ensure the fennel pieces have plenty of space to roast evenly. You can roast the fennel ahead and refrigerate until you are ready to add it into the casserole. Add the juices from roasting, if any, into the casserole too.
- Beans: I used haricot beans but you can use another bean variety if you prefer. I chose haricot simply because I wanted small beans that wouldn't dominate the sauce.
- Feta: You can swap the feta for a bit of grated cheddar or parmesan or omit the cheese altogether and enjoy this dish vegan.
- Herbs: I only used a little oregano but thyme, parsley or basil would make good alternatives. You can also use some herbes de Provence if you like.
- Storing: Any leftovers can be refrigerated for up to 3 days.
- Freeze individual portions for up to 3 months.
Serving suggestions
This easy vegetable casserole can be served with pasta, rice, quinoa or potatoes or simply a slice of bread and a drizzle of olive oil (olive oil tastes fantastic in this recipe!). Ideal for lunch or dinner, equally suitable as a family meal or a dinner party idea. Tastes great the next day too!

Hello, what could be used instead of white wine in here? Any similar taste replacements? I am really steering clear of all alcohol for health reasons. This looks good, let me know and I will be making. : )
Monika says
You could add water or vegetable/chicken stock instead.
Robin Lewis says
How would you recommend making the whole recipe (veg casserole w fennel and beans) ahead of time? Thanks.
Monika says
Hi Robin, you can make the entire casserole a day in advance without placing it under the grill (broil). Do this last step just before serving. Hope this helps:)
Christine says
Hello, is this recipe **Veg casserole with roasted fennel & beans ok to freeze?
Monika says
Yes it is!
Christine says
Thankyou. Am going to give this recipe try. I'm trying Vegetables I've never had before so am going to give Fennel a go. Will let you know how i go.
Christine says
Do you have any suggestions in what i xan use instead of Wine please?
Monika says
You can just omit the wine. Do let me know how it turned out for you!

Excellent recipe which was found searching "Vegan Fennel Recipes". Even though I am Vegan, I am battling weight issues brought on by medication so I am allowed limited fats = no oils. I have to steam stir everything - I am sure a good olive oil would add a nice richness, but it isn't necessary to have a great meal - I sprayed the fennel very lightly with some cooking spray.
I do not use wine and have learned that a splash of balsamic vinegar adds a little "winey" depth. I also added a little vegetable stock.
Being vegan I substituted "Betta than Feta" from "The Vegiterranean Diet" by Julieanna Heyer, MS, RD, to which I add a little salt for a more "feta" taste. I skipped the additional olive oil and did not bother with the final trip to the broiler since its main ingredient of tofu does not melt. Sprinkling the dish with parsley finished it off
Finally, I splurged and had a little Earth Balance Vegan Butter on homemade Sourdough Bread to go with the yummy casserole to make a complete protein. AND a steamed Artichoke dipped in Almondmilk Yoghurt Garlic Dill Dip (my invention).
I made the full recipe and am going to freeze half of the leftovers and add some vegan sausage to the remainder for another meal.

Thank you for sharing this Carrie. Well, there is always more than one way to make a recipe and you have certainly made it your own. I am glad it works for you. I especially like the idea of adding a little balsamic to the mixture.
Julia cavill Cavill says
I am vegan, and rather than use cheese-type substitutes in place of the feta, I used two generous tablespoons of nutritional yeast flaskes and they worked a treat. Totally delicious.
Monika says
So glad you made it work for you and thanks for the feedback!
Lynda wills says
I love this receipt and have made it loads now, I triple the ingredients and the next day I make a shepherds pie (vegan) out of if I also make a vegan pie too so it goes a long long way, I add lots of mushrooms and don’t add feta ☺️
Monika says
Thank you for letting me know Lynda, you sound like a super resourceful cook, great idea to turn the leftovers into a shepherds pie, should try it myself next time I make this recipe again:)
Lynn says
Really delicious, although I did find both the sauce and the fennel took a bit longer to cook, than stated. Maybe didn't chop the carrots small enough!
Monika says
Glad you enjoyed this recipe and thanks for the feedback:)
Julia cavill Cavill says
As the name suggests this was very easy to make and delicious to eat. I also added chia seeds and hemp seed hearts. Made twice in a week - once for myself, once for guests.
Monika says
So glad you enjoyed it and i love the super healthy extras! Thank you for sharing your feedback:)
Colleen says
What a unique and lovely side dish! I could eat this every day!
Monika says
Thank you! Glad you like it:) and thanks for stopping by!
Angela / Only Crumbs Remain says
Ooh wow Monika, this sounds (and looks) so delicious Monika. I have to admit that I've never tried fennel before (having had a 'memorable' evening with Pernod when I was just 20!) The thought of anniseed flavours still put me off, but as you've explained that the flavour changes when the fennel is roasted I feel the need to try your recipe. Pinning.

Monika says
Thanks Angela! Don't worry, the aniseed flavour in roasted fennel is very mild, nowhere near Pernod! Especially if you have it with other ingredients, as in this recipe.
FrugalHausfrau says
Monika, this looks gorgeous!! I'm pinning for later! 🙂
