Are you feeling overwhelmed by this year’s Holiday Season To-Do List too?

For hectic times like these, sandwiches are my go-to meal. They’re the trifecta of low-stress dinners: FAST. EASY. FILLING.

Right now, we’ve got this ooey-gooey grilled cheese with apple and Havarti on repeat. It’s satisfying without being heavy and has a great Fall Harvest Vibe going on.

The recipe’s super easy to customize. Here’s what we put in ours:

  • Crusty whole grain bread slices.
  • Good cheese – I like a creamy Havarti but smoked Gouda or even sharp cheddar would taste fantastic.
  • Half a crisp Granny Smith apple, the thin slices soften slightly during cooking.
  • Buttery walnuts for an unexpected crunch.
  • Greens! Peppery arugula is my favorite but baby spinach is a great option too.
  • Oh and fresh rosemary if you’ve got it on hand from making these snackable rosemary cashews

Bread slices topped with cheese, nuts and arugula.

Now, let’s talk condiments.

My husband likes a big smear of stone ground mustard on his sandwich. If you like things sweeter, apricot preserves or honey are excellent choices too.

During the holidays, I always reach for the leftover cranberry sauce or these balsamic roasted cranberries. The combination of apples + cheese + cranberries is irresistible!

Grilled Cheese with Apple and Havarti

Yield: 2 Sandwiches
Prep Time: 5 minutes
Cook Time: 8 minutes
Total Time: 13 minutes

A grown-up grilled cheese with crisp apple slices, arugula, and walnuts.


  • 4 slices Whole Grain Bread
  • 4 teaspoons Salted Butter, softened
  • 3 slices Havarti Cheese
  • 1/4 cup Walnuts, chopped
  • 1 cup Baby Arugula
  • 1/2 Granny Smith Apple, seeded and thinly sliced

Optional Condiments:


  1. Adjust toaster oven cooking rack to the lowest position. Place an ungreased baking sheet inside the toaster oven and preheat to 450°F on the “Bake” setting.
  2. Butter two bread slices and place buttered-side-down on a cutting board. Top each with a slice of cheese and layer with the walnuts, arugula, and apple slices. Tear the last slice of cheese into pieces and distribute evenly across both sandwiches. Spread remaining bread with your condiment of choice, place on top and butter outsides.
  3. Using oven mitts, carefully remove the preheated pan. Place sandwiches on the pan and return to the toaster oven.
  4. Cook sandwiches for about 4 to 5 minutes. Carefully remove the pan, flip sandwiches with a spatula and return to the toaster oven. Cook until the bread is golden brown and the cheese is melted about 3 to 4 minutes.
  5. Cool slightly, then devour.

During the summer, these Red Pepper, Carrot, and Hummus Sandwiches or Spicy Chickpea Edamame Salad Pitas are my go-to favorites. 

In the Spring, when leftover hard-boiled eggs are easy to come by treat yourself to a Sriracha Egg Salad Sandwich (With Garlic Kale Chips). They’re spicy, creamy and good for you too!

But in the cooler fall and winter months, nothing beats a warm and comforting toaster oven grilled cheese sandwich.

If you haven’t been using your toaster oven to make grilled cheese, you’re missing out.

The bread gets golden and toasted while the filling is perfectly warmed through. Plus, once you get the timing down for your little oven you barely have to pay attention while it cooks.

4 Toaster Oven Grilled Cheese Tips

  1. Preheat your pan. You should hear a sizzle (just like the griddle) when you add the sandwich to the pan.
  2. Use a good melty cheese like Havarti or provolone. Avoid shredded cheese, it tends to melt into the bread and disappear. 
  3. Don’t skip the flip. Flipping the sandwich halfway through the cooking time will ensure even browning and melting. 
  4. Layer on the flavor. Feel free to get creative and add your favorite condiments, vegetables, nuts, and fruit.

  1. This looks Devine. I always have a variety of good melting cheeses in my fridge. We have a food chain out here in the Seattle WA area called Grocery Outlet. Sells food stuff that are reaching their sell date, or have had packaging changed, or whatever the manufacturer did wrong to the packaging, like misspelled words. Anyway. there are all kinds of goodies if one is willing to search-from all over the world. Anyway, I go there for the cheese. Artisnal, varietal, American, and International. Amazing cheese at amazing prices. The most recent find was a whisky laced gouda. Can’t wait.

    My go to meal is grilled cheese in all it’s glory. WE get some amazing stuff from Wisconsin, a lot of it is organic as well. Anyway….These Ideas sound great. I have recently downsized my living space to a studio, and only have a toaster/convection oven.

    These are great tips for making grilled cheese in my toaster oven. I would never have thought of heating the pan and using the hot pa as the grilling surface. I was thinking I was forever going to have to have open-faced broiled grilled cheese sandwiches. Now there is a place for them, but….. And the idea of cranberry sauce. Smashing. I love it, make it myself, no-one else in my family eats it, and some always goes to waste. Now I know what to do with it. And apples and nuts? That is just nuts! I’m going to have a field day with your suggestions, thank you so much. Happy fall cooking….

    1. Hi Jiwa,

      That Grocery Outlet sounds like premium cheese heaven! I just looked and there might be one near us – thanks for the tip, I can’t wait to check it out.

      Always fun to meet a fellow grilled cheese fanatic 🙂 here’s a page with all the different ways you can try making them in your little oven (depending on the ingredients, some methods work better than others):

      Hope you have lots of fun with your grilled cheese experiments!
