Au Gratin Creamed Peas is a simple, cheesy side dish that pairs beautifully with any meal. The peas are smothered in a creamy sauce and topped with crispy breadcrumbs for that extra crunch.
Honestly, who knew peas could be so exciting? It’s like they dressed up for dinner! 😊 I love serving this dish warm, and it always makes my family smile, even the picky eaters.
Key Ingredients & Substitutions
Green Peas: Fresh or frozen peas add a nice touch. Fresh peas are sweet and vibrant, while frozen peas are convenient and still delicious. If you can’t find peas, you might substitute with green beans or even corn for a twist!
Butter: Unsalted butter is best for controlling the saltiness of the dish. You can replace it with olive oil or a dairy-free butter if you’re looking for a vegan option. I enjoy using herbed butter for extra flavor!
Heavy Cream: While cream gives a luxurious texture, you can omit it for lighter fare. If you want a creamy bite without the calories, use evaporated milk or half-and-half instead. I sometimes use Greek yogurt for a tangy kick!
Cheddar Cheese: Sharp cheddar takes center stage here, but you can experiment with other cheeses like Monterey Jack or Gouda for a different flavor. Additionally, adding a bit of cream cheese can enhance the creaminess.
How Do You Make a Smooth Sauce Without Lumps?
Creating a smooth sauce is all about patience and technique, especially with a roux. Here’s how to nail it:
- Start with melting butter on medium heat, then whisk in flour. Cook this mixture for just 1-2 minutes; this helps eliminate any raw flour taste.
- Gradually add warm milk while constantly whisking. This step prevents lumps from forming.
- Continue whisking for about 4-5 minutes until the sauce thickens. If it gets too thick, just whisk in a touch more milk.
Remember, the key is to keep whisking throughout for the smoothest results!

Ingredients You’ll Need:
For the Creamed Peas:
- 2 cups fresh or frozen green peas
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup warm whole milk
- ½ cup heavy cream (optional for extra creaminess)
- ½ teaspoon salt (adjust to taste)
- ¼ teaspoon freshly ground black pepper
- ¼ teaspoon garlic powder (optional)

How Much Time Will You Need?
This delightful dish takes about 10 minutes to prep and around 25-30 minutes to cook. You’ll spend some time getting your ingredients ready and then just let the oven do the work. So, in about 40 minutes, you’ll be enjoying your delicious Au Gratin Creamed Peas!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 375°F (190°C). This is important so that your dish bakes evenly and comes out golden brown.
2. Prepare the Peas:
If you’re using frozen peas, blanch them in boiling water for 2-3 minutes, then drain and set aside. If you have fresh peas, give them a quick steam or cook them lightly until they’re just tender. Your goal is to get them soft but not mushy!
3. Make the Roux:
In a medium saucepan, melt the butter over medium heat. Once melted, stir in the flour and cook it for about 1-2 minutes while whisking constantly. This will help you create a smooth roux which acts as the base for your sauce.
4. Add Milk and Cream:
Gradually whisk in the warm milk and, if you’re using it, the heavy cream. Keep whisking to avoid lumps forming, and let it cook until the mixture thickens and becomes smooth—this should take around 4-5 minutes.
5. Season the Sauce:
Now, it’s time to season the sauce! Add salt, pepper, garlic powder, and onion powder, if you like. Stir everything together well to make sure all the flavors blend.
6. Combine with Peas and Cheese:
Add the peas and half of the shredded cheddar cheese into the saucepan. Stir until everything is well combined and creamy. This is where the magic happens!
7. Transfer to Baking Dish:
Carefully transfer your creamy pea mixture into a greased baking dish. Make sure to spread it out evenly for the best results when baking!
8. Add More Cheese:
Sprinkle the remaining cheddar cheese evenly over the top of the pea mixture, then add the grated Parmesan cheese for that extra cheesy goodness.
9. Bake:
Pop your baking dish into the preheated oven and bake for about 20-25 minutes. You’ll know it’s done when the top is bubbly and lightly golden brown. Yum!
10. Garnish and Serve:
Once done, take it out of the oven and let it stand for a few minutes. This resting time helps it set up nicely. Before serving, sprinkle some chopped fresh parsley on top for a touch of color and freshness.
Enjoy your delicious, golden, cheesy Au Gratin Creamed Peas!
Can I Use Frozen Peas for This Recipe?
Absolutely! Just blanch them in boiling water for 2-3 minutes before adding them to the sauce. If you’re using fresh peas, simply steam or lightly cook them until just tender.
What Can I Substitute for Heavy Cream?
If you want to lighten the recipe, you can omit the heavy cream altogether and use more milk, or try half-and-half for a creamier texture without the full calories of cream. Greek yogurt can also serve as a tangy substitute!
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently on the stove or in the microwave, stirring occasionally for even heating.
Can I Make This Dish Vegetarian?
This recipe is already vegetarian-friendly! Just ensure that any cheese you use is rennet-free if you want to keep it entirely vegetarian. Enjoy the cheesy goodness without any meat!
