Not every comforting winter dinner needs to revolve around meat.
In fact, some of the most satisfying meals start with a tray full of vegetables, a handful of pantry staples, and a hot oven doing all the hard work.
This Balsamic Mushroom, Lentil & Feta Roast Tray is proof.
Roasted mushrooms become rich and savoury, balsamic vinegar caramelises into a sweet-tangy glaze, lentils add protein and fibre, and a sprinkle of feta brings just the right amount of creamy saltiness to tie everything together.
The result is a hearty vegetarian dinner that feels substantial enough for the coldest winter evening without leaving you feeling weighed down afterwards.
Best of all, everything cooks on one tray.
No juggling multiple pans. No complicated techniques. No mountain of washing up waiting for your future self.
Just simple, flavour-packed comfort food designed specifically for one person.
And honestly, that’s something worth celebrating.

Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to:
200°C fan-forced
Line a small baking tray with baking paper.
Step 2: Prepare the Vegetables
Place into a mixing bowl:
- mushrooms
- lentils
- onion
- carrot
- garlic
Add:
- balsamic vinegar
- olive oil
- thyme
- salt
- black pepper
Toss until everything is evenly coated.
The mushrooms may seem like a lot at first.
Trust the process.
They’ll shrink considerably during roasting.
Step 3: Arrange on the Tray
Spread the mixture evenly across the tray.
Try to keep everything in a single layer.
This encourages caramelisation rather than steaming.
And caramelisation is where the magic happens.
Step 4: Roast
Place the tray into the oven.
Roast for:
25–30 minutes
Stir once halfway through cooking.
The tray bake is ready when:
- the mushrooms are deeply browned
- the onions are caramelised
- the carrots are tender
- the lentils have slightly crisp edges
The balsamic should be glossy and rich.
Step 5: Finish & Serve
Remove from the oven.
Scatter over:
- crumbled feta
- chopped parsley
Optional:
Drizzle with a little extra balsamic glaze.
Serve immediately.
Serving Suggestions
This tray bake works beautifully on its own but can also be served with:

Or enjoy it straight from the tray while appreciating how much flavour mushrooms can produce when given proper respect.
