In a medium saucepan, combine the cream, broth, bay leaf, salt, and pepper. Add the onions and bring to a simmer over medium-high heat. Lower the heat to maintain a simmer and cook for about 20 to 25 minutes, until the onions are tender and the sauce has thickened and reduced slightly.
When the onions have become tender, add the peas and continue to simmer, stirring occasionally, for 5 more minutes until the peas are cooked and hot. Remove the bay leaf, stir in the butter and parsley, and turn into a serving bowl. Serve hot.
Notes
Creamed Onions and Peas will last for up to 4 days in a tightly sealed container. You can also freeze them in an airtight container for up to 2 months. Defrost in the fridge, and then gently reheat in a pot on the stove before serving. Stir frequently.You can also reheat the onions and peas in the microwave. Use short 30-second bursts and stir in between each heating period to heat them through more evenly.
