For the Roasted Onions:

For the Parmesan Cream Sauce:

  • 1 cup heavy cream
  • 1 cup grated Parmesan cheese
  • 2 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 teaspoon thyme leaves, chopped
  • Salt and white pepper to taste
  • Chopped parsley for garnish


  1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
  2. Prepare Pearl Onions: Peel the pearl onions, leaving them whole. Trim the ends, then toss the onions in olive oil, salt, and black pepper.
  3. Roast Onions: Spread the prepared onions on a baking sheet in a single layer. Roast in the preheated oven for 25-30 minutes or until they are golden brown and tender.
  4. Create Parmesan Cream Sauce: In a saucepan over medium heat, melt butter and sauté minced garlic until fragrant. Pour in the heavy cream and bring it to a gentle simmer.
  5. Incorporate Parmesan Cheese: Reduce the heat to low and gradually add the grated Parmesan cheese, stirring continuously until the cheese is fully melted and the sauce is smooth.
  6. Season and Add Thyme: Season the sauce with salt, white pepper, and chopped thyme leaves. Stir well to incorporate the flavors.
  7. Combine Roasted Onions and Sauce: Gently fold the roasted onions into the Parmesan cream sauce, ensuring each onion is generously coated.
  8. Serve and Garnish: Transfer the Roasted Parmesan Creamed Onions to a serving dish. Garnish with chopped parsley for a burst of freshness.

Cook Notes

Onion Size Variation:

  • If pearl onions are unavailable, you can use small cipollini onions or even shallots, adjusting the cooking time accordingly.

Creamy Consistency:

  • To achieve the desired creaminess, ensure the Parmesan cheese is of high quality and freshly grated. Pre-packaged grated cheese may result in a less smooth texture.

Thyme Substitution:

  • Rosemary or sage can be used as alternatives to thyme, depending on your flavor preferences.

Reheating Tip:

  • If preparing the dish ahead of time, gently reheat it on the stove over low heat, adding a splash of cream if needed to maintain the creamy consistency.


Caramelized Onion Twist

Before roasting, toss the onions in a bit of balsamic vinegar and honey for a sweet and tangy note. The caramelization intensifies the richness of the dish.

Gruyère Infusion

Replace Parmesan with Gruyère cheese for a nuttier flavor profile. The distinct taste of Gruyère complements the sweetness of the roasted onions exceptionally well.

Bacon and Onion Symphony

Enhance the dish by adding crispy bacon bits or pancetta to the Parmesan cream sauce. The smokiness of the bacon adds layers of savory goodness.

Keto Versions

Almond Flour Thickener

Incorporate a small amount of almond flour into the Parmesan cream sauce to achieve a thicker consistency while maintaining a keto-friendly profile.

Keto-friendly Sweetener

If a touch of sweetness is desired, use a keto-friendly sweetener like erythritol or monk fruit to balance the flavors without adding carbs.

Low-Carb Versions

Cauliflower Additions

Introduce roasted cauliflower florets to the dish, providing a low-carb alternative that absorbs the savory Parmesan cream sauce beautifully.

Coconut Cream Substitute

Replace heavy cream with coconut cream for a dairy-free and low-carb option. This substitution adds a hint of coconut flavor to the dish.

As we conclude this culinary exploration, the Roasted Parmesan Creamed Onions stand as a testament to the exquisite fusion of roasted sweetness and creamy richness. Whether you embrace the classic rendition or venture into keto and low-carb adaptations, the allure of this dish remains unparalleled. So, gather your ingredients, preheat the oven, and immerse yourself in the creation of a side dish that transforms onions into a symphony of flavors.
