It’s packed with vibrant, earthy flavours and comes with the added bonus of being as beautiful to look at as it is to eat. But don’t just take our word for it—let’s dive into the recipe!

Why This Tarte Tatin Is a Winner

This vegan tarte tatin features the earthy, rich flavours of roasted beetroot, caramelised red onions, and savoury sage—all wrapped in a golden, flaky puff pastry. The sweetness of the caramelised onions and the natural earthiness of the beets are perfectly balanced by the tangy zing of red wine vinegar and the warmth of dried sage. Topped with fresh chopped sage and orange zest for a bit of zing, this dish is sure to be a crowd-pleaser.

But it’s not just the flavours that make this dish a winner. It’s the way the dish is cooked. Tarte Tatin is traditionally made by cooking the filling in a skillet and then covering it with a pastry lid before baking. The beauty of this method is that once the dish is cooked, it’s flipped over, giving you a stunning, glossy caramelised topping. It’s like turning a humble vegetable dish into a work of art!

Plus, the best part? It’s completely vegan. No dairy, no eggs, just pure, plant-based goodness that everyone can enjoy. Whether you’re vegan, vegetarian, or simply looking to cut back on animal products, this recipe is a fantastic option for anyone.

If you’re not quite up for making this yourself, there are many easy-to-prepare, vegan frozen meals available that are delicious and ready to enjoy at home. But we digress—let’s get back to the recipe!

Ingredients You’ll Need

Before you get started, let’s gather everything you need to create this show-stopping vegan tarte tatin. This recipe is designed to serve four people, but you can easily scale it up or down depending on how many people you’re serving.

For the filling:

• 2 large beetroot, peeled and cut into wedges
• 2 medium red onions, peeled and cut into wedges
• 2 tbsp red wine vinegar
• 2 tbsp soft brown sugar
• 1 tsp dried sage
• A handful of fresh sage leaves, chopped
• Salt & pepper to taste
• Zest of 1 orange
• 3 tbsp olive oil

For the pastry:

• 1 block of vegan puff pastry (I used Jus-Rol, but any brand will do as long as it’s plant-based)

You’ll also need a medium-sized, ovenproof frying pan (or any oven-safe skillet you have) for the caramelising process. If you don’t have a frying pan that can go in the oven, a shallow ovenproof dish will work just as well.

How to Make Your Tarte Tatin

Ready to get cooking? Let’s dive into the method. Follow these simple steps and you’ll have a stunning tarte tatin ready to impress your guests in no time.

Step 1: Preheat the Oven

Start by preheating your oven to 200°C (fan), or 220°C (conventional). This is the temperature at which you’ll roast the vegetables and bake the pastry, so it's important to get the oven heated up in advance.

Step 2: Prepare the Beetroot and Onions

In a medium mixing bowl, combine the beetroot wedges, red onion wedges, red wine vinegar, soft brown sugar, salt, and ½ of the olive oil. Give everything a good stir to ensure the vegetables are evenly coated in the vinegar, sugar, and oil. The sugar will help caramelise the vegetables, giving them that lovely sweet richness.

Step 3: Roast the Vegetables

Next, place the beetroot and onion mixture in the ovenproof frying pan. Arrange them in a circle pattern (this helps with presentation when you flip the tarte later). Season with a bit of extra salt and pepper to taste. Cover the pan with a sheet of baking parchment and pop it in the preheated oven. Roast for about 30 minutes, or until the beetroot is tender and the onions have softened and begun to caramelise.

Step 4: Prepare the Pastry

While the vegetables are roasting, it’s time to roll out the vegan puff pastry. On a floured surface, roll the pastry until it’s about 1.5cm thick. Then, using your frying pan or skillet as a guide, cut out a rough circle of pastry that will fit over the top of the pan. Don’t worry about it being perfect—imperfections will only add to the rustic charm of your dish.

Step 5: Add the Pastry to the Vegetables

After 30 minutes, carefully remove the frying pan from the oven (use oven gloves, as it will be hot!). Gently place the rolled-out pastry over the vegetables, tucking the edges of the pastry down the sides of the pan. Don’t worry if it’s a bit messy or uneven; the pastry will puff up beautifully during baking, and that’s part of the charm.

Step 6: Bake the Tarte

Return the pan to the oven and bake for another 30 minutes, or until the pastry is golden brown and has risen to perfection. The pastry should be crisp and flaky, and you’ll notice a lovely caramelised edge where the vegetables have been cooking beneath the pastry. It’s at this point that the magic happens!

If you’re in a rush or simply prefer the convenience of having meals delivered, why not consider ordering delivered vegan meals straight to your door? You can enjoy delicious plant-based options without any effort required—perfect for a busy lifestyle.

Step 7: Flip the Tarte Tatin

Once the tarte is golden and baked to perfection, remove the pan from the oven and allow it to cool for 5 minutes. This gives the filling a chance to firm up slightly and makes flipping the tart easier. Then, using a palette knife, carefully loosen the edges of the pastry from the pan.

Next, take a plate and place it over the top of the frying pan. In one swift motion, flip the pan upside down so the tarte falls out onto the plate. Be careful here, as the contents will be hot and there’s a bit of a flip involved. If some of the onions or beetroot don’t fall into place, don’t panic! Simply rearrange them with a spoon, as the dish is still going to look gorgeous. The caramelised vegetables should form a beautiful glossy top.

Step 8: Serve & Enjoy!

Your Roasted Beet, Red Onion & Sage Tarte Tatin is now ready to serve! Garnish with a handful of freshly chopped sage leaves and a sprinkle of orange zest to brighten up the dish and add a bit of zing. Serve it warm and watch your guests marvel at the gorgeous colours and rich flavours.

Why Beetroot is a Superfood

In case you didn’t know, beetroot is more than just a tasty vegetable—it’s also packed with health benefits. Beets contain natural pigments called Betalains, which give them their beautiful deep red-purple hue. These pigments have been shown to have anti-inflammatory effects on the body, helping to reduce the risk of heart and liver diseases. Beetroot is also rich in essential nutrients like fibre, folate, and vitamin C, making it an excellent choice for anyone looking to boost their health.

In addition, beetroot has been linked to improved blood flow and lower blood pressure, thanks to its high nitrate content. So not only does it taste amazing in this tarte tatin, but it’s also good for you!

Scaling Up or Down

This recipe serves four people, but it’s incredibly easy to scale up or down depending on the number of guests you’re serving. If you’re hosting a large dinner party, simply double the ingredients and use a larger frying pan or ovenproof dish. Alternatively, if you’re cooking for just one or two people, you can halve the recipe and make a smaller version of the tarte.

Final Thoughts

This Roasted Beet, Red Onion & Sage Tarte Tatin is an excellent way to showcase seasonal vegetables in a show-stopping, plant-based dish. With its rich, earthy flavours and golden pastry, it’s bound to impress everyone around the dinner table. Whether you're enjoying it on your own or serving it at a dinner party, this recipe will definitely earn you some compliments.
