Why I’ll Love This Recipe

I appreciate how simple this recipe is to prepare while still making an impressive centerpiece for the table. The creamy filling is packed with flavor, and the crusty cob loaf becomes the perfect edible serving bowl. I also like that I can prepare the dip ahead of time and assemble it just before serving, making entertaining much easier.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Round cob loaf (sourdough or crusty bread)
Frozen chopped spinach, thawed and well-drained
Cream cheese, softened
Sour cream
Mayonnaise
French onion soup mix
Mozzarella cheese, shredded
Parmesan cheese, grated
Green onions, finely sliced
Garlic powder
Freshly ground black pepper

Directions

I preheat the oven to 350°F (175°C).
I slice the top off the cob loaf and carefully hollow out the center, leaving a sturdy shell. I tear the removed bread into bite-sized pieces for serving.
I squeeze as much moisture as possible from the thawed spinach.
I combine the cream cheese, sour cream, mayonnaise, French onion soup mix, mozzarella, Parmesan, spinach, green onions, garlic powder, and black pepper in a large bowl.
I stir everything until the mixture is smooth and evenly combined.
I spoon the dip into the hollowed bread bowl and place the filled loaf on a baking tray.
I arrange the reserved bread pieces around the loaf.
I bake for 25 to 30 minutes, or until the dip is hot, bubbly, and the bread is lightly toasted.
I serve the warm dip immediately with the toasted bread pieces and fresh vegetables if I want extra dipping options.

Variations

I sometimes add crispy cooked bacon for a smoky, savory flavor.
I enjoy mixing in chopped artichoke hearts for extra texture.
I occasionally use cheddar cheese instead of mozzarella for a sharper taste.
I like adding a pinch of crushed red pepper flakes for gentle heat.
I sometimes stir in chopped water chestnuts for an extra crunchy bite.

Storage/Reheating

I store any leftover dip separately from the bread in an airtight container in the refrigerator for up to 3 days. I reheat the dip in the microwave in short intervals or warm it in a 325°F (165°C) oven until heated through. If I have leftover bread, I warm it in the oven for a few minutes to restore its crisp texture. I do not recommend freezing the prepared dip because the creamy ingredients may separate after thawing.

FAQs

Can I prepare this dip ahead of time?

Yes. I often mix the filling up to a day in advance and keep it refrigerated until I am ready to fill the bread bowl and bake it.

Do I need to use frozen spinach?

No. I can use fresh spinach if I cook it first, let it cool, and squeeze out as much moisture as possible before mixing it into the dip.

What type of bread works best?

I prefer using a round sourdough cob loaf because its sturdy crust holds the dip well during baking, but any firm round artisan loaf works nicely.

Can I serve this dip without a bread bowl?

Yes. I can bake the dip in a casserole dish and serve it with crackers, toasted bread slices, tortilla chips, or fresh vegetable sticks.

How do I keep the dip from becoming watery?

I make sure to thoroughly drain and squeeze the spinach before mixing it with the other ingredients, which helps keep the dip thick and creamy.

Conclusion

I find this Spinach French Onion Cob Dip to be one of the best appetizers for sharing. The creamy, cheesy filling, savory onion flavor, and crispy bread bowl create a comforting dish that everyone enjoys. Whether I prepare it for a holiday gathering, game day, or casual get-together, I always appreciate how easy it is to make and how quickly it disappears from the table.
