Spinach Cheese Dip

There’s something about a bubbling dish of spinach cheese dip that instantly makes a room feel warmer.

Picture a shallow baking dish emerging from the oven, its golden, blistered cheese stretching in soft ribbons as you scoop in, the scent of garlic and warm dairy wrapping around you.

This is an easy, cozy appetizer—creamy, savory, and packed with tender green flecks of spinach—that comes together surprisingly fast, perfect for busy weeknights, game days, or impromptu get-togethers.

I still remember the evening friends dropped by unannounced; I’d almost nothing prepped, just a bag of spinach, some cheese, and cream. Twenty minutes later, that bubbling dip hit the coffee table with a pile of torn bread and cut veggies, and the whole mood shifted from frantic to relaxed.

It’s a lifesaver for casual gatherings, last-minute cravings, or effortless entertaining. Ready to bring this dish to life?

Ingredients

• 300 g frozen spinach, thawed and well-drained — squeeze very dry to avoid watery dip
• 240 g cream cheese, softened — room temperature blends smoothest
• 120 ml sour cream — adds tang and creaminess
• 120 ml mayonnaise — use full-fat for best texture
• 150 g mozzarella cheese, shredded — low-moisture melts evenly
• 80 g Parmesan cheese, grated — choose real Parmigiano-Reggiano if possible
• 2 cloves garlic, minced — fresh garlic gives better flavor than pre-minced
• 60 g yellow onion, finely chopped — dice small so it softens quickly
• 0.5 tsp salt — adjust to taste after baking
• 0.25 tsp ground black pepper — freshly ground for best aroma
• 0.25 tsp red pepper flakes (optional) — adds gentle heat
• 0.5 tsp paprika (optional) — sweet or smoked, per your preference
• 15 ml olive oil — for sautéing the onion and garlic
• 30 g mozzarella cheese, shredded, for topping — forms a melty top layer
• 15 g Parmesan cheese, grated, for topping — helps brown and adds sharpness

Step-by-Step Method

Set your oven to 180°C (350°F). Position a rack in the center for even heat circulation. Lightly grease an 8×8-inch baking dish or similar small casserole. This prevents sticking and makes cleanup easier. While the oven heats, gather your ingredients and equipment so everything is ready when you begin cooking.

Prep and Drain the Spinach

Thaw the frozen spinach completely. Place it in a colander and squeeze firmly with clean hands to remove as much water as possible. Press down repeatedly until the spinach feels almost dry. Proper draining prevents a watery dip and keeps the texture rich and creamy once baked. Set the spinach aside.

Sauté the Onion and Garlic

Heat olive oil in a large skillet over medium heat. Add the finely chopped yellow onion and cook for 3–4 minutes, stirring occasionally, until softened and translucent.

Stir in the minced garlic and cook for about 30 seconds until fragrant. Remove the skillet from the heat to prevent the garlic from browning too much.

Mix the Creamy Base

Place softened cream cheese, sour cream, and mayonnaise into a medium mixing bowl. Beat or stir vigorously until the mixture is smooth and well combined.

Make certain there are no lumps of cream cheese. A smooth base helps the other ingredients blend evenly and creates a silky, cohesive dip texture.

Combine Aromatics with the Base

Add the warm onion and garlic mixture to the creamy base. Stir thoroughly to distribute the aromatics throughout.

Mixing while the onions are still slightly warm helps them blend into the cream mixture. Make sure no clumps of onion remain. This step builds savory flavor in every bite of the finished dip.

Fold in Spinach, Cheeses, and Seasoning

Add the well-drained spinach, shredded mozzarella, grated Parmesan, salt, black pepper, red pepper flakes, and paprika to the bowl. Fold gently with a spatula until everything is evenly incorporated.

Ensure the spinach is dispersed throughout so each scoop has greens and cheese. Taste the mixture and adjust the seasoning slightly if desired.

Transfer and Top the Dip

Spoon the mixture into the prepared baking dish. Spread it into an even layer, smoothing the surface with a spatula.

Sprinkle the extra shredded mozzarella and extra grated Parmesan evenly over the top. Cover all areas to promote a bubbly, golden crust during baking and ensure a nicely melted cheese finish.

Bake Until Hot and Bubbly

Place the baking dish on the center rack of the preheated oven. Bake for 18–20 minutes, or until the dip is hot, bubbly around the edges, and the top is lightly golden.

Avoid overbaking, which can cause the dip to separate. Remove the dish carefully using oven mitts. Let it rest for 5 minutes before serving.

Ingredient Swaps

• Use Greek yogurt in place of sour cream and/or mayonnaise for a tangier, lighter dip; neufchâtel can replace cream cheese for less fat.
• Swap mozzarella with Monterey Jack, white cheddar, or a local mild melting cheese; Parmesan can be replaced by Grana Padano or a hard aged local cheese.
• For vegetarian (non‑rennet) needs, choose cheeses labeled “microbial” or “vegetarian rennet”; for gluten-free, just pair with gluten-free crackers or veggies.
• No frozen spinach? Use ~450 g fresh spinach, sautéed until wilted and well-drained, then chopped.

You Must Know

– Flavor Boost – For deeper flavor, add an extra 10–15 g Parmesan and a small squeeze of lemon (about 5 ml) *after baking*; the extra umami and acidity sharpen the cheesy taste without increasing salt too much.

Serving Tips

• Serve in a warm skillet with toasted baguette slices or crusty bread.
• Pair with tortilla chips, pita chips, or pretzel bites for varied textures.
• Offer fresh veggie sticks—carrots, celery, bell peppers—for a lighter dipping option.
• Garnish with chopped chives or parsley and an extra sprinkle of Parmesan before serving.
• Keep warm in a low oven or small slow cooker for longer gatherings.

Storage & Make-Ahead

Spinach cheese dip keeps in the fridge for up to 3–4 days in an airtight container.

You can fully assemble it a day ahead, then bake before serving.

It also freezes well for up to 2 months; thaw overnight in the refrigerator, stir, then reheat until hot and bubbly.

Reheating

Reheat gently to keep dip creamy.

In microwave, warm in 20–30 second bursts, stirring.

In oven, cover and heat at 160°C.

On stovetop, use low heat, stirring constantly.

Game Day Party Classic

Once you know how to keep this dip warm and melty, it turns into the kind of game day hero everyone hovers around.

I’ve watched entire conversations stall out mid-sentence as people go back for “just one more scoop.” The spinach keeps things hearty, the mozzarella stretches into those glorious strings, and the Parmesan adds that nutty, salty finish you taste even over the roar of the game.

When I’m setting up a spread, this dip anchors the table.

I like to ring it with dippers so everyone finds a favorite:

• Tortilla chips for that satisfying salty crunch
• Toasted baguette slices for a chewy, golden base
• Crisp veggies for a fresh, cool contrast to the molten cheese

Frequently Asked Questions

Can I Make This Spinach Cheese Dip in a Slow Cooker or Instant Pot?

Yes, you can. I’d mix everything, then warm it on LOW in the slow cooker or Instant Pot’s sauté/warm setting, stirring often. I miss the oven’s browned top, though—it’s creamier, cozier this way.

Is This Spinach Cheese Dip Suitable for Vegetarian or Gluten-Free Guests?

Yes, it’s naturally vegetarian and gluten-free as written, assuming your cheeses, mayo, and sour cream are certified. I always double-check labels, then serve with gluten-free crackers or veggies so every guest can dig in.

How Can I Lighten This Recipe for a Lower-Fat Version?

You can lighten it by using Neufchâtel instead of cream cheese, Greek yogurt for sour cream, and reduced‑fat mayo and mozzarella. I’ve done this for weeknights, and friends never noticed—it still tastes luxuriously creamy.

What Are Some Creative Ways to Repurpose Leftover Spinach Cheese Dip?

I’d spoon leftovers into omelets, stuff them into chicken breasts, spread them on grilled sandwiches, swirl through pasta, or dollop onto baked potatoes—like discovering a secret, cozy sauce hiding in last night’s party bowl.

Can I Safely Keep This Dip Out at Room Temperature During Parties?

No, I wouldn’t leave it out more than 2 hours; dairy dips spoil fast. I set a small bowl on the table, keep the rest chilled, then swap in a fresh, warm batch halfway through.
