Preparation
Cut 500 g of broccoli into florets, peel the stem, and slice it. Blanch in boiling salted water for 3 to 4 minutes, so it still has a clear bite. Plunge immediately into ice water, this stops the cooking and locks in the color. Toast 40 g of sliced almonds in a dry pan over medium heat for 2 to 3 minutes until golden, then transfer to a plate. In the same pan, slowly melt 50 g of butter and keep heating until it turns light brown and smells nutty (brown butter, beurre noisette), about 3 minutes. Lower the heat immediately, add the drained broccoli and 1 finely chopped garlic clove, and toss for 2 to 3 minutes until the broccoli is warmed through and lightly browned. Season with salt, pepper, the zest of half an organic lemon, and 1 tbsp of lemon juice, fold in the almonds, and serve.
Why brown butter loves broccoli
Butter changes dramatically when heated: the milk proteins brown (the Maillard reaction) and create aromas reminiscent of toasted nuts, caramel, and toffee. That is a perfect match for broccoli, which brings a gentle bitterness, the nutty butter rounds out that bitterness without masking it. Lemon brings the freshness back, and sliced almonds double down on the nutty note. A classic pairing that deserves to land on more dinner plates.

How can I vary this side dish?
With Parmesan: grate 30 g of Parmesan over the warm broccoli, a cheesy Italian take. With chili: add a pinch of dried chili flakes to the butter, spicy and Mediterranean. With anchovies: melt 2 finely chopped anchovy fillets into the butter, umami-rich and great with lamb. With pine nuts: swap the almonds for pine nuts, a bit pricier but even more buttery in flavor. With tahini: add 1 tsp of tahini to the pan in place of the almonds for a Middle Eastern note that pairs well with grilled chicken.
Tips for foolproof broccoli
- Do not discard the stem, peeled and sliced it is the best part.
- The ice-water shock matters, it keeps the broccoli crisp and bright green.
- Watch the butter closely, only seconds separate nutty from burnt.
- Toast the almonds first and set them aside, otherwise they will burn in the butter.
- Add the lemon zest at the very end, or the aroma will fade.

FAQ
Can I use frozen broccoli?
Yes, but it will turn out softer and less crisp. Sauté the thawed broccoli straight in the pan with the brown butter and skip the blanching step. Use slightly fewer almonds and a touch more lemon to make up for the lost freshness.
Can I make it vegan?
Swap the butter for a good olive oil or coconut oil, the nutty brown-butter note is lost but the recipe still works vegan. A tablespoon of nutritional yeast brings back some of the buttery depth.
Can I reheat or prep ahead?
Blanch the broccoli a day in advance and keep it in the fridge. Toast the almonds separately and store them in a jar. On serving night, just warm everything through in the pan with fresh brown butter, ready in 5 minutes.
