Baked Asparagus

Dinner

Perfectly roasted green asparagus with whole garlic cloves that turn sweet and sticky in the oven. The asparagus gets tender with crispy, caramelised tips whilst the garlic mellows into something you'll want to squeeze out and spread on everything. Finished with a squeeze of fresh lemon and flaky salt. Simple and seasonal.

Ingredients 

1x2x3x?

• 500 gr green asparagus fresh green asparagus, medium thickness works best,
• 3 tbsp olive oil or 40g melted butter
• 4 cloves garlic
• 1 lemon
• salt and black pepper
• fleur de sel optional, for finishing

Equipment

baking tray

baking mat or parchment paper

double spatula

Instructions

1. Prepare the asparagus

• Preheat your oven to 220°C (200°C fan)/425°F/Gas Mark 7. You want it properly hot.

  Wash the asparagus and pat dry. Hold each spear at both ends and bend gently, it'll snap naturally where the woody bit ends. Chuck the woody ends. If the asparagus is particularly thick, you can peel the bottom third with a vegetable peeler, but it's not essential.

2. Season and arrange

• Lay the asparagus on your baking tray in a single layer. Don't pile them up or they'll steam instead of roast.

  Drizzle with olive oil (or melted butter if you're feeling French about it). Season with salt and pepper. Toss with your hands to coat everything evenly.

  Scatter the whole garlic cloves amongst the asparagus. They'll roast alongside and become sweet and sticky.

3. Roast

• Bake for 12-15 minutes, depending on thickness. Medium spears take about 12 minutes. Fat ones might need 15.

  You want tender asparagus with some caramelised bits and slight wrinkling. The tips should be starting to crisp up. If they're still bright green with no colour, give them another 2-3 minutes.

4. Finish and serve

• Transfer to a serving plate whilst still hot. Squeeze over fresh lemon juice. If you've got fleur de sel, scatter a pinch over the top.

  Squeeze the roasted garlic cloves out of their skins and eat them with the asparagus. They'll be sweet and sticky, not sharp.

  Serve immediately. This doesn't sit around well, it's best straight from the oven.

Notes

• Pencil-thin asparagus will overcook and turn sad. Fat spears take longer but stay tender inside. Medium thickness is the sweet spot.
• Don’t overcrowd your baking tray. Give the asparagus space or they’ll steam rather than roast. Use two trays if needed.
• Butter vs olive oil. The French would use butter. Olive oil is easier and tastes brilliant. Your choice.
• Add parmesan? You can, but it’s not French. Grated parmesan in the last 2 minutes of roasting is lovely, but it’s veering into Italian territory.
• Make it fancy. Shave over some parmesan after roasting, add toasted pine nuts, or drizzle with balsamic reduction. But honestly, the simple version is usually best.

About this recipe

Asparagus season in France is treated with high regards. When it arrives, it really arrives and for about six weeks every market stall, every greengrocer, and every restaurant menu is organised around it. My local market goes from nothing to mountains of the stuff almost overnight, and the moment I see it I start making this baked asparagus for lunch until it disappears again.

Not because it’s the most impressive thing you can do with asparagus, but because it’s the most honest and when you bake asparagus in the oven with good olive oil, garlic and lemon, you can really appreciate the taste of them. That’s the whole baked asparagus recipe basically. And when the asparagus is properly seasonal, it’s one of the best things you can put on a table.

White asparagus versus green asparagus

The French relationship with asparagus is actually two separate relationships, and it’s worth understanding the difference. White asparagus, which arrives in markets from April onwards, gets the full ceremonial treatment. It’s thick, pale, grown underground to keep it tender and mildly sweet, and it’s steamed carefully and served with hollandaise or mousseline sauce.

Green asparagus is different as it grows above ground and develops that characteristic grassy, slightly bitter flavour, that handles bold treatment well. Roasting became increasingly popular in France as green varieties became more widespread over the last few decades, and it changed things. High heat concentrates the flavour, caramelises the tips, and produces something with considerably more character than steamed asparagus will ever manage. This baked asparagus recipe is built entirely around that logic.

Garlic, garlic, garlic

The whole garlic cloves roasting alongside the asparagus are a specifically French touch worth knowing about. If you leave them whole and unpeeled, they roast gently in the heat rather than burn, and they turn soft, sweet and almost jammy inside their skins. You can squeeze them out and eat them alongside the asparagus, or mash them directly into the olive oil on the tray and use it as a sauce. Either way, they transform from sharp raw garlic into something completely different and utterly delicious.

Getting the best result from your oven baked asparagus

The equipment matters more here than in most vegetable recipes. A thin, overcrowded baking tray will steam the asparagus rather than roast it. You will need direct even heat and enough space for the spears to lie flat. I use a De Buyer stainless steel baking tray for this, with a baking mat underneath the asparagus. The stainless steel conducts heat evenly across the whole surface, so the asparagus caramelises consistently from tip to stem. And the baking mat means nothing sticks and cleanup takes about thirty seconds. De Buyer has been making professional French baking equipment since 1830, and for a recipe this simple, the right tray really does make a difference.

When to buy asparagus

Asparagus season runs from May to June in France, maybe slightly earlier in warmer regions. Outside that window, the asparagus in supermarkets has typically travelled a long way and sat in cold storage for longer than it should have. They are fine too, but it is still not the same thing as when you buy them in season. When asparagus are in season, the tips are tight and the stems snap cleanly rather than bending. And that satisfying snap is what you are looking for. If the stems bend, I recommend leaving them and going back in a week when the next batch arrives.

This asparagus in the oven recipe is designed around seasonal asparagus, and that is when it is worth making. Buy it when it is good, make this, and eat it immediately while it is still warm from the tray.
