📝 Ingredients
Serves 4🥬Fresh Produce(3)
- 4 garlic cloves, minced
- 1 large onion, thinly sliced
- Seasonings (1 tsp each): paprika, garlic powder, salt, pepper, italian seasoning (5 ml)
🥛Dairy & Eggs(3)
- 2 tbsp butter (28 g)
- 1 cup of cream or coconut milk, room temperature (240 ml)
- 1/2 cup fresh Parmesan cheese, grated (120 ml)
🫙Pantry Staples(2)
- 1 tbsp olive oil (15 ml)
- 8 oz (225g) pasta of your choice (227 g)
🍯Sauces & Condiments(1)
- 1 tbsp soy sauce, optional (15 ml)optional
📦Other(1)
- 2 tbsp chili crisp (30 ml)
👨🍳 Instructions
- 1
Slice your onion like it owes you money, mince that garlic (use fresh please), and measure out all your seasoning. Bring a cup of cream or coconut milk to room temperature.
- 2
Heat 2 tbsp butter + 1 tbsp olive oil in a large skillet over medium. Add in the onions and let them vibe for 15–20 minutes, stirring occasionally, until golden and jammy. If they start sticking, hit ‘em with a splash of water.
- 3
While your onions are caramelizing like sweet little angels, boil a pot of salted water and cook the pasta until al dente. Drain, but don’t forget to save some of that pasta water, it’s liquid gold.
- 4
When the onions are deeply golden, stir in your minced garlic and all the seasonings. Let it all bloom for a minute, then add the chili crisp and saute for a minute. Pour in your cream (or coconut milk). Let it simmer and get cozy for a few minutes then add the grated Parmesan cheese.
- 5
Add your pasta to the sauce and toss to coat. Use that reserved pasta water to loosen things up if it’s too thick… you’re going for silky, not sticky.
- 6
Serve hot with an extra spoon of chili crisp on top for a spicy kick and maybe a sprinkle of fresh parsley if you’re feelin’ fancy.
💡 Pro Tips
- ✓Caramelize onions at exactly medium heat (300-325°F pan surface) because higher temps create bitter compounds instead of sweet Maillard reactions, and the process genuinely takes 20-30 minutes despite what recipes claim.technique300-325°F
- ✓Add garlic only in the final 60-90 seconds of onion caramelization because garlic burns at 280°F while onions need sustained heat above 300°F to properly caramelize.timing60-90 seconds
- ✓Reserve 1 cup of starchy pasta water before draining because it contains 2-3% dissolved starch that acts as a natural emulsifier to bind your cream sauce without breaking.technique2-3% starch content
- ✓Bring cream to room temperature (65-70°F) before adding to prevent thermal shock that causes proteins to curdle when hitting the hot caramelized onions.ingredient65-70°F
- ✓Use a 12-inch skillet minimum for this recipe because onions need single-layer contact with the pan surface to caramelize properly rather than steam in their own moisture.equipment12-inch minimum
