Method
Heat your oven to 200°C (400°F). Line a large baking sheet with parchment.
Peel the butternut squash, halve it lengthwise, and scoop out the seeds. Cut into 2cm cubes. Wipe the mushrooms clean and quarter them.
Toss the squash and mushrooms together on the baking sheet with 3 tbsp olive oil, 1 tsp salt, and black pepper. Strip the thyme leaves from the sprigs and scatter them over. Spread in a single layer without crowding.
While the vegetables roast, brush the bread slices on both sides with the remaining 1 tbsp olive oil. Heat a large frying pan over medium-high heat.
Toast the bread in the dry pan, pressing lightly, about 2 minutes per side until crisp and marked with golden patches. Transfer to plates.
In a small saucepan over medium-low heat, melt the butter completely. Add the minced garlic clove and cook 30 seconds, until fragrant but not browned.

Safety & Storage
Cooking Temperature
Roast vegetables at 200°C (400°F) until squash is tender and mushrooms are caramelized. The high heat ensures proper doneness of the vegetables.
Handling
When melting butter for the mustard butter sauce, use medium-low heat and watch carefully. Butter can go from melted to burnt quickly when combined with garlic.
Cross Contamination
Use separate cutting boards and utensils for raw vegetables and ready-to-eat bread to prevent cross-contamination.
Allergen Warning
This dish contains milk (butter), wheat (bread), and mustard. Inform guests of these allergens before serving.
Storage
Roasted vegetables can be refrigerated in an airtight container for up to 3 days. The mustard butter should be refrigerated separately and reheated gently before use.
High Risk Population
Ensure mushrooms are cooked thoroughly. Undercooked mushrooms pose a higher risk for elderly, immunocompromised, pregnant individuals, and young children.
Equipment Safety
When toasting bread in a dry pan, press lightly and monitor closely. Dry high-heat cooking can cause oil residue in the pan to smoke or splatter.
This dish is best served immediately after assembly. The toasted bread will lose its crispness if left sitting, and the mustard butter is most flavorful when warm.
Pro Tips
Technique
Don't crowd your baking sheet. I know it looks like you're wasting space, but the mushrooms need room to steam themselves into sad, rubbery versions of what they could be. Give them at least 2cm between each piece so they caramelize rather than sweat.
Substitution
Sourdough works beautifully here if you want something with more chew and tang. Any sturdy bread that can hold its structure under the vegetables will do—the goal is toast, not a sponge.
From the chef
I developed this recipe after watching yet another restaurant take perfectly good roasted vegetables and stand them upright on a board like some sort of produce pride parade. These toasts don't need to be an event. They're just excellent food that happens to be appropriate before noon—caramelized squash, earthy mushrooms, and a mustard butter that bites back. No velvet ropes, no waiting for a table, no reservation fee. Just breakfast.
