📝 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 (around 300°F pan surface) because higher temps create bitter compounds instead of sweet Maillard reactions that develop over 15-20 minutes.technique300°F surface temp
- ✓Add garlic only in the final minute of onion caramelization because garlic burns at 280°F while onions need sustained heat around 300°F for proper caramelization.timing1 minute final addition
- ✓Reserve pasta water at a 3:1 ratio (3 parts sauce to 1 part pasta water) because the starch content creates proper emulsification and prevents the cream from breaking.technique3:1 ratio
- ✓Bring cream to room temperature before adding because cold dairy added to hot aromatics causes immediate protein coagulation and creates a grainy texture instead of smooth sauce.ingredientRoom temperature
- ✓Use a 2:1 butter to olive oil ratio for caramelizing because butter provides milk solids for deeper browning while olive oil prevents the butter from burning at extended cooking temps.technique2:1 ratio
