I love scalloped potato casserole dishes. . and love to vary them up all the time. Last year, I topped my potatoes with sliced tomatoes and now, I seem to do this all the time. I love the freshness and burst of flavor that the tomatoes add.
Easter is right around the corner so I wanted to add a little something special. . so I added my favorite pesto in between the potato layers.
You guys have to try this! This casserole dish is not only stunning but it’s also delicious! Seriously so much flavor with the pesto!! This would be perfect for your upcoming Easter brunch!
I hope you check out my post and the recipe, posted over at

- 1/4 cup parsley
- 2 to 3 cloves garlic
- 1/4 cup pine nuts

- 1/2 cup Parmesan cheese
- Kosher salt to taste
For the scalloped potato casserole:
- PAM Original Cooking Spray
- 3 to 4 large unpeeled Russet potatoes; washed and cut into 1/8-inch thick slices for best results, use a mandolin slicer

Instructions
For the pesto:
- Coat your food processor with PAM Canola Oil Cooking Spray. Combine the basil, arugula, parsley, garlic, and pine nuts in a food processor and pulse until coarsely chopped.

This looks seriously good. Talk about taking something classic and making it even more incredible! I love the pesto on this. And tomatoes are always welcome. Always.
Scalloped potatoes remind me of the days when I helped serve Easter dinner at church. There would always be tons of different styles of scalloped potatoes and I would try to taste every single one. I adore this recipe and definitely think it’d be a hit at Easter dinner this year.
Ooo I love this! It still feels hearty for winter, but with that bright pesto flavor it’s also spring-perfect!
