Equipment
Method
- Bring the water to a boil in a 3-quart saucepan over high heat.
- Add the frozen onions and simmer for 5 to 7 minutes, until tender.
- Drain the onions and set them aside.
- Melt the butter in the same saucepan over medium heat.
- Stir in the flour and cook for 1 minute, stirring constantly.
- Gradually whisk in the milk and heavy cream.
- Simmer for 3 to 5 minutes, whisking often, until the sauce is smooth and thick enough to coat a spoon.
- Stir in the onions, sage, thyme, salt, and pepper.
- Cook gently for 2 minutes, until the onions are heated through.
Notes
Whisk the milk and cream in gradually to keep the sauce smooth. Refrigerate leftovers for up to 3 days; freezing is not recommended because the cream sauce may separate. For a dairy-free variation, use plant-based butter, milk, and cream.
