Instructions
Caramelized Onions
- Melt butter in a skillet over medium-low heat. Stir in onions and salt. Let cook undisturbed for about 10 minutes.
- Sprinkle with sugar and stir. Allow to continue cooking until browned and softened, stirring occasionally every 8 to 10 minutes. This should take about 60-70 minutes total.
Polenta
- In a saucepan, bring stock to a boil over medium-high heat. Constantly stirring with a wooden spoon, slowly pour in cornmeal.
- Reduce heat to low. Cover and cook for 30 to 40 minutes, vigorously stirring about every 10 minutes. The polenta is done when the grains soften to your liking.
- Turn off heat and stir in Parmesan and butter until they melt. Add heavy cream, salt and pepper. Stir in caramelized onions.
- You can serve polenta immediately or pour into a buttered dish for baking. If baking, let the polenta set until it firms in texture, or put it in the oven after about 10 minutes to keep the creamy consistency but develop a crust. Bake at 375 degrees for about 20 minutes.
Blue Cheese Sauce
- Melt butter in a skillet. Sprinkle flour over butter and constantly whisk for three minutes.
- Pour in heavy cream, garlic and Dijon mustard while whisking to prevent lumps. Once warm, stir in blue cheese until it's somewhat melted but with some crumbles intact.
- Season with salt and pepper to taste. Prepare this about 10 minutes before the polenta is ready.
- Spoon blue cheese sauce over polenta and enjoy!
Notes
- The caramelizing of the onions takes the longest—roughly 60-70 minutes total. Be patient with this step for maximum sweetness and flavor.
- You can prepare the polenta ahead by pouring it into a buttered dish and refrigerating overnight. Remove about 30 minutes to 1 hour before baking to prevent cracking.
