👨🍳 Instructions
- 1
Preheat the oven and spread the sliced onions in a baking dish. Season with salt, pepper, paprika, and olive oil, then place the garlic head in the center and drizzle with olive oil.
- 2
Bake until the onions are deeply caramelized and golden brown and the garlic becomes soft and tender.
- 3
Squeeze the roasted garlic from its skin and mix it with the roasted onions. Add the lemon juice, spinach, parsley, vegan cream, and a few ladles of reserved pasta water, stirring until smooth and creamy.
- 4
Add the cooked pasta and gently toss until every piece is coated in the creamy caramelized onion sauce. Add more pasta water if needed to reach the desired consistency.
- 5
Taste and adjust the seasoning if needed, then serve warm garnished with fresh parsley and an extra squeeze of lemon.
💡 Pro Tips
- ✓Bake onions uncovered at 400°F for 45-55 minutes, stirring every 15 minutes, to achieve deep caramelization without steaming; moisture must evaporate for the Maillard reaction to occur, which creates complex umami flavors.timing400°F, 45-55 minutes, stir every 15 minutes
- ✓Use a 4:1 ratio of pasta water to cream (6-9 ladles water to 200ml cream) because starch in pasta water emulsifies with fat and helps sauce coat pasta evenly; vegan cream has lower fat content (~10%) than dairy, requiring extra starch stabilization.technique4:1 ratio (starch:fat)
- ✓Reserve pasta water before draining because it contains 6-8% starch that acts as a thickener and emulsifier; add it gradually while tossing to reach sauce consistency rather than adding all at once, which risks over-thinning.ingredient6-8% starch content
- ✓Toss pasta with sauce off-heat for 30-45 seconds to allow starch granules to hydrate and thicken the sauce without breaking down vegan cream's already-delicate emulsion through prolonged heat exposure.timing30-45 seconds off-heat
- ✓Wrap the garlic head's top (cut side) in foil while roasting to prevent browning and bitterness; unprotected cut faces expose sulfur compounds that polymerize at high heat, creating harsh flavors rather than sweet, nutty ones.techniqueFoil-wrap cut surface
